Re: RFE String interpolation for RPG

[Vern Hamberg <vhamberg@xxxxxxxxxxxxxxx>]

I don't remember whether the 3rd parameter of %scanrpl has to be a 
variable, or can it be an expression. If the latter, one can always nest 
the BIFs = not pretty but all in one, right?

But an interesting RFE, let's see how many votes and what the comments 
are. This looks kind of like C's printf function, conceptually, anyhow. 
Hey, you CAN maybe call that! Should see if I can put that in my 
presentation!
