Invoking CTTTPI From Another Program

When calling CTTTPI as a program from within another program

Pass input parameters for CTTTPI using DD statement SYSIN only. Do not specify input parameters in the JCL EXEC statement.
Linkage and parameter passing conventions for the CTTTPI utility are the same as for IBM utilities. For more information, refer to the IBM Utilities Manual.
The CTTTPI utility supports substitution of DD names for its SYSIN and SYSPRINT statements using the same parameters used by IBM utilities. For more information, refer to the IBM Utilities Manual.

When constructing jobs that invoke CTTTPI, copy the DD statements from the CTTTPI JCL procedure as follows:
