It's also like PHP, where if you use quotes, variables and escaped characters within the quotes are evaluated, but if you use apostrophes, they are not.

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")
