WAIT WAITM (PC) 10 24 16 Provides/terminates supervisor linkage to
user's PC routines. Under CMS/DOS, if a
program check occurs in a simulated
transient routine, a check is made to
determine if linkage to an AB routine
has been established. If it has, control
is passed to the AB routine. If not, the
program is canceled. If a program check
occurs in a program other than a
simulated transient, and if linkage has
been established to a PC routine, control
is passed there. If no PC routine is
available, a check is made to see if
linkage to an AB routine has been
established. If so, control is passed to
the AB routine. If no PC or AB routine
is available, the program is canceled.
(IT) 18 No operation performed.
(oe) 20 No operation performed.
(AB) 37 Provides/terminates supervisor linkage to
(PC)
user's AB routine for abnormal
termination of the routine. Manv of the DOS/VS abnormal termination codes are not
meaningful under CMS/DOS. Control is
given to an abnormal termination routine
on the following selected hexadecimal
co des: 1 A , 20 , 2 1, 22, 2 5, 2 6 , 27, 2B.
17 Return from user's PC routine.
(IT) 19 Not supported. Execution terminates with
an error message. (OC) 21 Not supported. Execution terminates with
an error message. (AB) 95 Return from user's abnormal task
termination routine.
TEeB control block generated. However, CMS/DOS does not support the use of the
Timer Event Control Block.
52 Zero seconds are returned in register 0 as
the time remaining in the interval. 07 wait for I/O completion.
29 Not supported. Execution terminates with
an error message. Figure 34. DOS/VS Macros Supported under CMS (Part 2 of 3)

SAVE=savearea operand is ignored by CMS/DOS. No operation performed. IPasses control from a program to a I specified entry point in another program. I IStores the contents of specified reqisters I in the save area provided by the calling I program. I tRestores registers whose contents were I saved and returns control to the calling I program.
