SMU_Assign_Delete_
message_number
is an integer expression that identifies an ASSIGN message. message_number
must be a value greater than 0.
portion
is the identifier of an ASSIGN message integer part to delete. portion is one of:
portion_bytes
is the size of portion, in bytes, and must be a value greater than 0. For TAL, you
must supply this value; for COBOL and FORTRAN, the compiler implicitly
computes and transmits this value to the function. If
portion_bytes exceeds the
number of characters in
portion, the first unused character of portion must be
a space character.
Return Value
SMU_Assign_Delete_ returns one of the following values:
ACCESS Access mode—0 for read-write, 1 for read-only, 2 for write-
only, and 3 for extend
BLKSIZE Block mode size
EXCLUSION Exclusion mode—0 for shared, 1 for protected, and 3 for
exclusive
FILECODE File code
PRIEXT Primary extent size
RECSIZE Record size
SECEXT Secondary extent size
TANDEMNAME Guardian file name
*ALL* The entire ASSIGN message
Return
Value Meaning
0 The operation is successful.
-1 The operation failed because of a logic error, such as:
•
message_number or portion_bytes has an invalid value.
•
The specified ASSIGN message does not exist.
•
portion does not identify a defined deletable part of an ASSIGN message.
-2 The operation failed because making changes would invalidate the backup
process.
