Hi,

I had faced two interview questions which i don't know.

1) what is the max length of a parm that we can pass from a jcl to a program.

2)what are all the ways we can pass memory from one cics prgm to another cics prgm apart from TSQ and DFHCOMMAREA.

Thanks
Madhu

Just a quick follow-up to Question #1. Many folks seem to infer that because the JCL limit for the PARM= statement is 100 characters that the same is true for the program. That is not the case, as the program will accept a length much greater for the parameter(s).

Hi Superk,

I couldn't understand the explanation you mentioned.

Can you please explain it clearly?

Thanks

Madhu,

Using Pointers is one more option wherein you don't pass the entire bunch of data between two programs. Pointers are used to save the amount of memory used by a program and also to cut down on the amount of data transferred b/w two programs - finally to improve program efficiency/productivity.

I have seen few programs using this pointer concept - but was a bit lazy to explore on those. I will probably try to find out an example for you.

Thanks,
Phantom

Hi Phantom,

Thanks for your efforts.

I know we can share memory thru DFHCOMMAREA,TSQ,TDQ and pointers, but I heard from interviwer that there is around 7 ways where we can share memory.

I will let u know in case if find more on this.

Thanks
Madhu
