Re: RFE String interpolation for RPG

It doesn't strike me as a "huge" effort, since it can be implemented
as syntactic sugar for concatenation or %SCANRPL, plus %CHAR. (In
other words, help people do what they are already doing, but easier to
write, easier to read, and less error-prone.) For those who do a lot
of string processing, it is significantly more convenient than
existing alternatives.

I think, that some sort of "string interpolation" would be a good thing. Especially when building dynamic SQL this can help, to make code much more readable.

Scott Klements idea of a new "quote" type is a really good - like the x'1F' strings - lets say, take f'.....{variable}.....' strings.

And as always in RPG, one can use it, or not it.

And the implementation can be easy - whether you replace that with %scanrpl calls, or you implement it C-sprints-like - either way will work, and I think the compiler team will find a good and fast implementation.

I would say - lets write a RFE!
