C$SetEnv

Sets or clears the value of an environment variable.
Note: When calling this routine, ensure you are using the 1024 calling convention.

Setting the value of an environment variable with C$SetEnv updates the corresponding environment variable immediately in the process space of the current run unit. Thus, when the RM/COBOL run-time system uses environment variables for such actions as file access name resolution, the call to C$SetEnv will have an immediate effect on that run unit.

Syntax:

CALL "C$SetEnv" USING name, value [, return]

Parameters:

name
PIC X(n)
value
PIC X(n)
return
PIC 9(n) BINARY, where n can be a digit from 1 to 9

On Entry:

name
The name of the environment variable to set or clear.
value
The value to which the environment variable is set. A value of SPACES indicates that the environment variable should be deleted.

On Exit:

return
The result code returned from the call: zero for success and non-zero for failure.

Comments:

On UNIX, environment variable names are case-sensitive. On Windows, environment variable names are not case-sensitive.
