Is it possible to run a REXX program in background, if so how to execute it please explain

[Robert Sample]

Terminology is critical in IT, where similar terms may mean very different things. Your term "background" is not clear. Are you talking about :

1. running a batch job under z/OS that will execute a REXX program?

2. running a Unix System Services background task that will execute a REXX program?

3. invoking the REXX program in some other way?

8.3 Running an exec in a Non-TSO/E address space.

8.5 Running an exec in the TSO/E address space.

i want a rexx job to be executed in background that will check the volume status,ie once it is revoked it has to run continousily in background.

[stevexff]

Now I think I'm even more confused. Did you mean 'invoked' rather than 'revoked'?

Why don't you lell us what you are trying to achieve, rather than how you are trying to do it? Then we can advise you of the simplest and most appropriate way to do it. Which may not be REXX at all...

[syamcs]

sorry its invoked. that is if it is executed that rexx program has to run for continousily in background

[Robert Sample]

it has to run continousily in background.

On a mainframe this is a started task. It is extremely unlikely that your REXX code will run as a started task, which has very strict guidelines as to how they are written and used.

Perhaps you wuold be better served by telling us WHAT you want to do, not HOW you want to do it. 99.999% of the time when someone posts here that they want something to run continuously, it is because they do not understand the mainframe environment and do not realize that running something continuously on a mainframe is a BAD IDEA!

sorry..... if i have mentioned any thing wrong....
my requirement is to create a rexx tool to check the amount of space utilized by a particular volume and this tool should check the volume.

my requirement is to create a rexx tool to check the amount of space utilized by a particular volume and this tool should check the volume.

the only result of the requirement is to waste resources
if somebody in your organization had received a less than minimum storage administration training
he/she should know that the requirement can be met by using ISMF!

no waste of resources, no reinventing the wheel!

thank you... for your suggestion...
but this was an assignment given to me.....
