ARexx Including One Script Into Another

tygre · 02 December 2022, 04:13

Hi all!

Another ARexx question

Is it possible to include one ARexx script into another? Something like include in C? (I scoured the Internet but couldn't find an answer...)

Thanks!

You can use CALL to run another script. Or, if the other script shall return a value, you can just call it as a function. But you cannot share global variables. Every data has to be transferred as parameters and return values.

And if you need, you can use message ports for interaction among different scripts.

Hi Thomas and Daxb!

Thanks for your answers!

I actually wanted to avoid either solution because I would need to pass data to the other script, which would require to PUSH/QUEUE data, which would be as long as the small piece of code that I want to "share" across many scripts

That's okay, I'll duplicate some (little) code across scripts, not such big a deal even if it's not DRY...

Thanks!

There is also SETCLIP(), RXSET and GETCLIP() to share global variables (simpler then message ports). I use this for three scripts to share small data. Read the explanation of this functions/command in ARexxGuide2. There is also an example "Global variables on the clip list".
