INTRODUETION
when a system/3 user decides to upgrade to a system/37} or an rBM 4300
Processor, he eneounters a eertain number of difficurties. First,
System/3 RPG, in which most user programs are written, iloes not have the
same functions as DOS/VS RPG. Second, wit-hin a short time the user has
to ehange not only his programs, but also the control eards and physical
location of the files.
IBM has made the System/3 to DOS/VSE Conversion Aid International Fiel<1
Program available in order to help the System/3 user convert to DOS/VSE
and allow him to prepare for the conversion using his Systernrz3. In this
wiy, while using tools familiar to him, he can have his programs reaily
for exeeution when his Systen/3'l} or 4300 is installed.
It is recomnended that System/3 seguential files without additions to
the end of the file and treated consecutively be converted to SAM files-
Otherwise files should be eonverted to VSAM files.
gNPERSTANDING HE PROGRAM
T
The System/3 to DOS/VSE Conversion Aid International FieId Program
consists of 19 source programs writt-en in System/3 RpG and one resiilent
program written in DOS,zVSE ssembler language.
A The DOS/VSE program
should be catalogued into the DOS/VSEreloeatable Iibrary. This routine
serve as a complement to the converted System/3 programs when the chosen
met-hods is VSAM' and it is used to aecess on ESDS VSAM file or to aecess
the Data conponent of a KSDS VSAM file by relative record number.
llE_gggrgMrzER
The first four programs to be executed make up the customizer; two of
these programs can be executed on a System/3 Model 10 anrl the ot-her two
on a System/3 Model 15-B- The fcLlowinq is c n o c i f i o A -
o Usinq the S ! - I I T C Hc a r d :
- Control statement input on 80- or 96-column cards or on
diskette
- Customized output of the conversion aid programs on 80- or
96-column cards, diskette, or magnetic tape
- Output of the components to be cataloged on the DOS/VSE
relocatable library on 80-column cards, diskette, or magnetic
tape.
Configuration of the System/3 on which the eonversion programs are
to be executed:
- Input of the programs to be eonverted to 80- or 96-eolumn
eards or diskette
- Type of disk unit for work files
- Output of the eonverted programs (includinq control eards for
cataloging and printer carriage control tapes) cn B0- or
96-column cards, dlskette, or magnetic tape
- Output of the input job stream for execution under DOS/VSE on
80- or 96-column cards, diskette, or magnetic tape.
. Correspondence between System/3 deviees and System/31l deviees
r Description of Systen/310 or 4300 configuration:
- Type of disk (3330,33t{0 or FBA)
- Type of printer
- Printer line length (default value)
- Printer overflov line (default value)
- System/3'| 0 PO\,iER/VS(incl-uded or excludedf
Thi.s customizer will call an input file that contains the remaining
components of the conversion aid nr^dram
If this customizer needs to be executed on a System/3 Model 15-C or 15-
D, programs CST151 and CST152, residents in source Library, must be
compiled. The SUBR93subroutine, needed to eompile CST151 program, is
cat-aloged in R I..ibrary.
pRCGRAM
!HE_SONVERSION
CONVOO nd CONVO1, the first
a two components of the aetual conversion
program, prepare the definition and caleulate the occupancy of all the
files of the prograns to be converted-
The CONVOO ontroL cards specify the characteristies
c of all files: the
type and narne of each file, the length and number of records, and so on.
C O N V O 1p r o v i d e s a l i s t i n g of file occupancy of the logical units, and
places on a work file the informaticn reguired by subseguent components.
Sequential disk files can be converted to SAM or VSAM-ESDS. Direct-
files can be converted to VSAM-RRDS ith relative
w record number-
Inilexeil files can be converted t o V S A M - K S D So r V S A M - E S D Sw i t h alternate
indexes (if the file is created unordereil).
The CONV02 component reads the System/3 source programs. If these
programs are compatible with the file definitions, and if there are no
other unresolvable incompatibilities, C O N V O 2p l a c e s t h e m i n a w o r k f i l e -
C O N V O 2i s t h e o n l y c o m p o n e n t t h a t i s e x e c u t e d e a c h t - i m e a s o u r e e p r o g r a m
j-s converted- If a program is not aecepted, only that program need be
resubmitted.
It is assumed that all prcgrams to be converted have been execute<1
without errcr on the System/3. The CONV03 to CONV05 eomponents convert
all the source programs in a job stream placed in the work file by
C O N V 0 2 - C O N V O 5p l a c e s t h e c o n v e r t e d souree programs on the type of
media specified in the customizer.
The listings produced for each converted program contai-n:
. A listing of the converted program
o Modifications performed by the conversion aid program
r Moilifications assumed by default and which must be verified
. Functions that the program cannot convert and whieh must be
converted manually-
The conversion airl prograrn contains a large number of components in
order to execute it on a System/3 16K partition.
The programs converted using components CONVOO o CONV05 can be executed
t
under Dosi/vsE. The remaining eornponents perform the followinq
functions:
o Creating printer carriage control tapes
r Distributing files on disk
. Preparing the conversion of System/3 files to System/37O via
intermediate tape files or Data Import Feature
r Defining catalog, space, and VSAM files
. Preparinq the input iob stream for execution.
CREATING PRINTER CARRIAGECONTRCI TAPES
The CoNVO6 cornponent- processes printer carriage control tapes. First,
it reduces their number to a minimum; then it numbers them, starting
wittr the nurnber speeified in the input t-o the coNVO4 eonponent. rn
addition, it gives a name to each tape and lists its format. The
component generates the control and ilata statements used to eompile and
eatalog all the FcBs, unless an IBM 1403 printer without powER/vs is to
be used-
DISTRIBUTING FIIES CN DISK
T h e C O N V O 7c o m p o n e n t d i s t r i b u t e s files on disk. A data statement must
be entered to coNv0? for each sYsxXX definect in coNVoo to relate the
SYSXXX to the volume number and to indicate the relative position in
which the disk space of the paek must be allocated- If these statements
contain no errors' coNvOT produces an oceupancy list similar to the one
produced by eoNvO1- This list indicates the files on each paek which
may eontain one or several sysxxx. coNvo7 produces, too, a listinq of
t'he DLBLs and TIBLs in alphabetical order aieording to labels and with
blank file names.

INS'TALLING THE PROGRAM
The magnetic tape containing the system/3 to Dos/vsE conversion Aid
International Field Frogram may he restoreil directly ont-o an IBM 5q4q
Disk storage Drive, or into the 54t14 simulation area of a 3340.
When the disk has been restored, it will contain:
. An objeet library in which are cataloged the eST101 anil csT102
components (for a systemT3 Model 10) and the esr151 and esr152
components (f or a system/3 l'lodel 158) . These components make up
the eustomizer, according to the systen/3 model on whieh they are
to be executed. The SUBR93 subroutine is eataloqed in the R
Sublibrary.
. A source library, in which is cataloged the souree CST'ISI and
csr152 components to be compiled in case a system/3 Model 15-c or
15 - D , i s u s e d i n t h e customizer step-
. A file containing all the conversion components and the routine to
be cat-aloqed in the Syst_en/3'l} or 4300 processor.
ggq:IQf4-IZTNG rHE PRoGRAM
The customizer components are executed only once and modify the
definitions of the different files used for conversion. In addition,
they retrieve the conversion components from the 5444 disk and plaee
them, together k'ith the routines to be cataloged in DoS/vSE Reloeatable
Library , onto the rnedium specified in the SWITCH staternent. These
components can then be compiled and cataloged in the System/3 used for
the eonversion process-
Output can be on 80- or 96-column cards, diskette, or magnetic tape.

To customize the source program before beginning the eonversj-on process,
the following data must be entereil for the CST101 or CST151 component,
depending on the System/3 model used and on the 1/O medium indicated in
the SWITCH staternent:

Notes:
The 5444 sirnulation area of a 3340 disk does not support random
access to inilexed files. si-nee the rnternational Fierd program
uses ranrfom access to indexecl files, this area eannot be used as a
conversion work area. Therefore, positions 10 to 1? of the cNV
statement can be used only for an actual 5444 disk unit.

2. If a System/3 card reader punch is replaeed by two clifferent
DOS/VSE devices, two EQU statenents must be used, with the same
code in positions tt to'1 0 and different ones in positions 1'l to 17.
? The first EQU statement read by the customizer will be considered
as the definition of the input unit and the second as that of the
output unit. If there is only one EQU statement, the coile in
positions 11 to 17 will be considered as the definition of the
input/output unit.
sBeqEssrNg
In the input to CONV00, there must be one F statement for each labeled
tape file or disk file used by the programs to be converted. If CONVOO
is executed without error, C O N V O 1w i t l be executed; if not, the control
statements must be corrected and CCNVOO erun. r

includes a NAME-IABEI statement for eaeh labeled tape or disk file used
by the program, followed by a // statement and the source program to be
converted. If a program is rejected (an explanatory message is
displayed at the printer) , it will not be added to the file of converted
programs and must be reconverted-

CONV05 produces the converted source programs, together with the eontrol
statements required to conpile them and catalog them in the DOS/VSE- In
addition, it produces a listing of the converted source programs, with
the nurnber of the corresponding error messages. The text of the
messages is given at the beginning of each proqram listing.
Messages numbered 25 and above are rwarning messages, and no aetion is
reguired- Hovever, a speci-a1 processing routine for sequential files
will be cataloged in the DOS/VSE Relocatable Library in response to
