Well, I have written some C and I'd have to say it isn't so bad. In the world
of ILE, I'd guess it is six of one, half a dozen of the other for compiler
performance (as they both reach pcode stage before compile).

C programmers have to do more work for file/field handling than RPG
programmers. But, if you are using embedded SQL (which a C programmer may be
familiar with from other platforms), there isn't that much to it.

That doesn't mean I'd suggest it as first choice, but if a guy has the C skill
and the option of putting a C compiler on, it is a consideration. 

Other considerations might include the likelyhood that any packages purchased
by your company will probably be in RPG. If you plan on supporting other
software within your enterprise, it will probably be easier just to move to RPG.

How often can you afford to be unexpectedly out of business?
