Just curious, why not RDi? Is it because of the cost? In that case, are you only looking for free editors?
Personally, I love RDi.
I have heard of some free editors like RPG Nextgen, but maybe you get what you pay for...?
Yes, unfortunately it's not part of the budget currently so my boss wants to see what else is out there. I am sure he'll agree to some cost just not the cost he is being quoted for RDi. Seems like every shop I have been in there is a distaste for WDSC/RDi and now with the cost of RDi seems like I'll be waiting forever to get a taste of the future.
If you want a GUI product (that runs on Windows) then RDi is your only real choice. But there are some 3rd party things out there, and (I think) there is a no-charge RPG add-on to Eclipse (Eclipse is what RDi is based on and is free).
If you want a green screen alternative to PDM, then IBM now ships another product which is the exact same code as PDM but with a different name. I believe its calld ATM. So instead of STRPDM, you do STRATM ( I think I have that "ATM" thing wrong, so maybe someone else can clearify what that product name is) Basically they've discontinued PDM/SEU for new customers and offer this other version that does NOT include the compilers or SEU.
check out brad stone's object tool which you can download and try before you buy.
If your shop has been around a while, you might have a set of CDs with websphere left over. Dust em off and if you have version 6 it includes the last version of free wdsc before RDi came out. If you managed with PDM so far, wdsc will offer all you need and more at no extra cost. With an IBM donwloadable fix, it will even run fine on W7.
