Q:

What are the difference between in-stream procedure and inline procedure in JCL ?

Answer

An in-stream PROC is defined right in the jcl stream and doesn't reside in the proclib. This is an older technique associated with punched cards but it is still in use with setup and installation programs from vendors.


for the in-line perform instead of:


perform add-paragraph until switch = 'y'


you can code


perform until switch = 'y'


body of code


end-perform


body of code is the code from add-paragraph appearing in-line (ie right in the perform) instead of in a separate paragraph (out of line code)
