Can Rexx replace clist

Postby GeorgeQ » Thu Jun 22, 2017 5:02 am


Rexx is upgrade version of Clist, My question is if REXX an totally replace/cover clist?

Because I want to learn rexx/clist. Can I skip clist and only learn rexx will that be enough to handle both rexx and clist knowledge?

Clists and Rexx are 2 diffferent languages - one is not an "upgrade" of the other.
Concentrate on Rexx - it is easier (to me anyway) and pfobavly more powerful. You can also get a version that can run on your PC at home so you can learn outside of work hours.

Beware, though - the mainframe version your file handling is different from the PC. On the mainframe you use an external function - EXECIO. On the PC you can use the Linein and Lineout or Charin and Charout. OORexx on the PC has a minimal version of EXECIO.
The problem I have is that people can explain things quickly but I can only comprehend slowly.

I agree with Nic. There are few special cases where CLIST is better, but in general REXX is by far the better product. And much easier to work with too.
