CALL ISPLINK parameters

These parameters are positional. They must appear in the order described for each service.

Parameters shown below the line are optional, but ISPF assumes default values for those parameters you do not choose.

If you want to omit a parameter, you must still account for it by inserting a blank enclosed in single quotes (' ') in its place. This is how you would omit parm2 from this sample call:

CALL ISPLINK (service-name, parm1, ' ', parm3);

If you need only the first few of a list of parameters, you must omit all other parameters to the right of the last parameter you need. For example, if you are using a service that has five parameters, but you need to use only the first three, code it like this:

CALL ISPLINK (service-name, parm1, parm2, parm3);

You must show the last parameter in the calling sequence with a ‘1’ as the high order bit in the last entry of the address list. PL/I, COBOL, Pascal, and FORTRAN call statements automatically generate this high-order bit. However, you must use the VL keyword in assembler call statements.
