SYSPUNCH (SYSPCH for z/VSE) content

This output contains the disassembled source program. Statement names begin in column 1, mnemonics begin in column 10, operands in col 16, and an occasional comment begins in column 44. A sequence number (by tens) is in columns 73–80. Comments are included to show the macro name associated with SVCs, and other statements are flagged to aid in identification of certain operations:

Instruction / Addresses: Comment
BALR 14,15: std linkage
BALR x,0: address set
other BALRs: non-std linkage
BASR 14,15: std linkage
BASR x,0: address set
other BASRs: non-std linkage
BAL 0,xxx and BAL 1,xxx: parm set brch
BAL x,xxx: perform
BAS 0,xxx and BAS 1,xxx: parm set brch
BAS x,xxx: perform
STM instructions: save regs
LM instructions: restore regs
BCR 15,R14: exit
absolute location hexadecimal 10: CVT address
absolute location hexadecimal 4C: CVT address
other absolute locations: PSA reference
EX instructions: run instr opcode
L instructions: reference to ADCONS

When used explicitly in instructions, registers are denoted by:

Access Registers by A0, A1,...A15.
Control Registers by C0, C1,...C15.
Floating Point Registers by F0, F1,...F15.
General Purpose Registers by R0, R1,...R15.
Vector Registers by V0, V1,...V15.

An ASMDREG macro is generated at the end of the program to create the appropriate EQU statements for the symbols defining the Access, Control, Floating Point, General Purpose, and Vector registers. If any DSECTs were defined in the SYSIN file, they are near the end of the source program. ASMDREG is installed by default in PRD2.PROD. Check with your systems programmer if HLASM Toolkit was installed in a different sublibrary.
