CICGETV: call to get, set, or drop a REXX variable
CICGETV calls this linkedit stub subroutine from an assembler REXX/CICS command routine, to retrieve from, set ,or drop REXX variables in the REXX program that issued the command.
Operands
- varname_addr
- specifies the address of a character string containing the name of the REXX variable. The variable name (that this address points to) must be in uppercase.
- varname_len
- specifies the length of the variable name.
- data_addr
- specifies the fullword address where the address of variable contents are.
- data_len
- specifies the length of area pointed to by data_addr (fullword).
- function_name
- specifies the particular CICGETV function to be performed. There
are three choices:
- GET
- retrieves the address and length of a REXX variable.
- PUT
- creates or replaces a REXX variable.
- DEL
- deletes a REXX variable.
Note:
- Immediately before any call to the CICGETV linkedited routine stub, register 10 must be loaded with the value of the RXWBADDR field in the passed parms (CICPARMS).
- If a get request is issued for a variable that does not exist, the value returned is the same as the variable name.
- CICGETV uses a standard save area convention with R13 pointing to an 18 fullword length area. R1 points to a standard parameter list. R14 contains the return address. R15, upon entry to CICGETV, returns CICGETV's entry point. Upon return, R15 contains the return code.
- The CICGETV module is located in the REXX/CICS distribution library.
- A return code of zero is reflected to indicate the success of the operation, or a decimal 99 indicating an internal error (such as a storage limit exceeded situation).
