So I am trying to write some external subroutines in assembly to run along with a driver program that I wrote. I want to read in the program, through sysin, and also provide some instream assembly.
Here's the JCL part:
//SYSIN DD DSN=***.***.***,DISP=SHR
//*
//* SUBROUTINES HERE?
//*
/*
I understand the basics of entry and exit linkage, but do I need to have another DD statement for my instream assembly? Or, could I just start coding after I declare my ***.***.*** data set?
If you want to have some code in a dataset and some other code in-stream, you can do that in your JCL as follows...
//SYSIN DD DISP=SHR,DSN=BLAH.BLAH
// DD *
[in-stream data]
//*
...but @Bill Woodger asks a good question, why not assemble the subroutines separately and link them in. Personally, I would find that more "normal."
