The TSO/E Service Facility supports the call invocation formats for PL/I, COBOL, FORTRAN, PASCAL, and Assembler. Therefore, you should use the syntax that is appropriate for the language you are using.

The language you choose may include language-specific constructs for invoking external programs. For example, PL/I contains the FETCH statement to get dynamic addressability to external programs. You may choose to use these statements. Other languages may have compiler options that allow for dynamic invocation of subroutines. Use these methods, if possible, to avoid link-editing TSOLNK with your application program. See also Passing Control to IKJEFTSR.
