page of GC20-1807-7 As Updated April 1, 1981 by TNL GN25-0829 SUPERVISOR ftACROS CMS/DOS supports physical IOCS macros and control program function
macros for DOS/VS. Figure 33 lists the physical IOCS macros and
describes their support. Figure 34 lists the control program function
macros and their support. Refer to VMlJIQ Volume 1 for details of the macros'
operation. r I Macro I I CCB (command I control block) I I EXCB (execute I channel program) WAIT SECT VAL (sector
value) DTFPH IThe CCB is generated. I Support IThe REAL operand is not supported; all other I operands are supported. ISupported. Issued whenever your program requires I an I/O operation (started by an EXCP macro) to I be completed before execution of program I continues. ISupported for VSAft.

control to an entry point. I I I I GENL Generates a directory list with a 34-byte I entry for each of the specified phases. I LOAD I Iyirtggl MacrQ§1 SYS=YES or NO operand is ignored. 04 Reads any phase into storage and returns
control to the calling phase.
