CL Programming


Passing Parameters

The TFRCTL command can be used to pass parameters to the program being called in the same way the CALL command passes parameters, but with these restrictions:

In the following example, PROGA calls PROGB and passes two variables, &A and &B, to it. PROGB uses these two variables and another internally declared variable, &C. When control is transferred to PROGC, only &A and &B can be passed to PROGC. When PROGC finishes processing, control is returned to PROGA, where these variables originated.
