Yeah, printf puts the output on stdout, do I remember right, sprintf puts the output to a variable? That'd do just what the OP wants. I found some examples with google of using printf instead of DSPLY, some since 2002 -

https://www.ibm.com/support/pages/coding-rpg-iv-beginners-tutorial - printf is one example here, in a larger recent tutorial

I assume that with mulitple *NOPASS parameters to cover every instance you anticipate, you are good to go. sprintf might become my good friend!!

printf works fine Vern. You have to decide how many parms you want to accommodate as RPG has no notion of a repeating parameter ...

sprintf too.

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!

Not exactly. This does it all in one statement; with %scanrpl you would have to do it once for each variable you want to replace, then print the resulting string.

myString = 'I have {apples} apples and {bananas} bananas';
myString = %scanrpl('{apples}' : %char(apples) : myString);
myString = %scanrpl('{bananas}' : %char(bananas) : myString);
print myString;

Isn't that exactly what %ScanRpl does?

Description:

Add string interpolation support so variables can be inserted into string
literals without having to use concatenation with + symbols and multiple
literals.

For example:

apples = 4

bananas = 3

print(f"I have {apples} apples and {bananas} bananas")
