Hi,

I am new to assemblers. I have a to enlarge the size of variable.
Is there any sizeof operator which gives the size of variables?
And how to display the value of any register in spool?

Please Help

Hello,

Suggest you locate the variable in question in the source and modify it according to the new length.

Possibly there is more that you have not posted . . .

There is an L' length operator, but it's not exactly a sizeof function. Perhaps if you more fully explain what you want, you'll get better answers.

And the fastest, easiest way to print register values most likely is the SNAP dump macro instruction. Check the Assembler Services Guide manual in the MVS bookshelf (http://www.ibm.com and navigate to the z/OS libary) for details on what's required to use it.

Hello,

I just noticed the subject for this topic. . .

How does the subject relate to the question posted?

And i missed the second question. . .

Hi all,

Actually I need to change the size of some datasets from bytes to megabytes.
But I first wanna to display the size of datasets to know the actual size of datasets.

So i am looking if there is any instructions that can show the value of registers to spool.

I have used:

WTO TEXT=(R8),MF=(E,WWTO)

and

WWTO WTO TEXT=,MF=L List form

size of dataset or variable?

@Nic: its datasets

What does this mean?

Actually I need to change the size of some datasets from bytes to megabytes.

Are you planning on deleting and redefining the data sets? If so, why are you posting in the Assembler section since that would be a JCL issue? If not, I think you need to clarify exactly what it is your are wanting to do because so far you're making absolutely no sense, and you've asked about several extremely different things.

Sorry but it is Nic not @Nic. This is not bird-song or where-ever this @ thing started.

Hello,

Actually I need to change the size of some datasets from bytes to megabytes.

Suggest you post the current allocation of a couple of these files.

As Robert mentioned, what you want is not clear and you need to clarify.
