The input to DFHSMSCP, set up by the macro used for the
invocation, or directly by the calling program, consists of the
following TCA fields:
- TCASCTR--the storage control request byte.
This can contain one of the following values:
- X'80' GETMAIN, in conjunction with:
- X'40' Initialize storage
- X'20' Conditional
- Storage class in bits 3 through 7 (the resulting SMMC GETMAIN
storage class name is given in parentheses where this differs
from the first name):
- X'00' 1WD, treated as SHARED
- X'04' LINE
- X'05' TERMINAL or TERM
- X'0C' USER (becomes CICS24)
- X'0D' TRANSDATA or TD
- X'13' SHARED (becomes SHARED_CICS24)
- X'14' CONTROL
- X'40' FREEMAIN, in conjunction with:
- X'01' TCTTE address supplied.
- TCASCIB--the 1-byte value to which storage is to be
initialized.
- TCASCNB--the 2-byte field giving the number of bytes
requested on the GETMAIN.
- TCASCSA--the 4-byte address of the storage that was obtained
or the storage to be freed.
