Hi,

Can we change the Static call to dynamic call and ice versa while executing the program? Your help is appreciated.

No. The determination of static versus dynamic call is made at COMPILE time. At execution time, there is no way to change the call type.

No not possible unless you compile the program dynamically each time.As Robert said it is not possible to change it during execution.

Thanks Robert and PB.

Why would you want to? You'd suddenly start using a different loadmodule from a previous CALL, and not have the previous WORKING-STORAGE values.

What kind of situation might this support?

I'm trying to understand the concept actually. At times it's advisable to have the dynamic call and other its advisable to have static, that made to ask this question. Possibly the question did not make any practical sense but it does help me...

I do not believe i agree . . .

What IS advisable is to follow the standards of the organization where the code is being implemented. . .

There is no such thing as better option. As Dick says, you should follow your shop standards.

Say if you have a COBOL Date-validation module that gets called from a million other modules, you'd use a dynamic call. If the date-validation module in turn calls some Assembler routine, it can be statically link-edited into the Date Module.

I agree to your points, as I said I was just rying to understand the concept.

THanks for your replies.
