A JCL SET statement value can also be passed and resolved as a PARM= string, so it is possible to write a program in your favorite language that takes the PARM= value and writes the data to a DD allocation in a job-step. And if you must have multiple data lines substituted, for example as SYSIN, use multiple job-steps with DISP=NEW for the first step and DISP=MOD for each additional job-step.
At one site I support, this technique is used to build IDCAMS control statements for execution.
