Calling CSP applications from z/OS XL C

To call a CSP application from z/OS® XL C, you must:

  1. Define the CSP program to be called one of the following:
    • DCGCALL - calling under MVS/TSO
    • DCGXFER - transferring control under MVS/TSO with OS pragma linkage
  2. Fetch the program dynamically.
  3. Transfer control to the program. You must pass at least one parameter when calling CSP from z/OS XL C. This is the pointer to the ALF name and application name.
