I'm curious what your response was. The limit is the limit, and I wonder why they would ask such a question?

By using the PARM parameter we can pass 100 bytes... 98 characters and 2 bytes for passing length...

Glad to hear that you find it out what interviewr was looking for, but quite surprising at this stage... Smile

Why don't you play around a bit with ACCEPT verb to know what you asked for?

yes we need seperate accept statement for each line in sysin data. I think max limit to pass sysin data is 137 characters

for JCL PARM its 100 characters.

if we want to pass more we use the "call... using" for the same program instead of JCL-PARM .... limit to passing data through CALL-USING is 32K characters

last one is through external variables for which the limit remains 64K characters

if we want to eliminate the size limit i.e. still need more data... we pass using the files or database
