File No. 5360-21 Form C28-68ll-1 44PS Systems Reference Library IBM System/3S0 Model 44 Programming System Assembler Language This publication contains specifications for the IBM System/360 Nodel 44 Programming System Assembler Lan- guage. This assembler language is used to write programs for the Model 44. The IBM System/360 Model 44 Program- ming System Assembler program processes the lanquage and provides auxiliary functions useful in the prepara- tion and documentation of a program.
