To accommodate CMS files, the format of the distribution tape for the compiler
and library has been revised. The new format is described in the "Installation
Procedures" sections.
Additional Compiler Default Options
New' Programming Feature
The ADSIZE and CMSIZE options have been added to the FORTRAN macro
instruction. They control the default size of the compiler address constant table
(NADCON) and the backward connection table (CMAJOR). Information has been
added to the section "Coding the FORTRAN Macro Instruction".
