RE: RFE String interpolation for RPG

Meant to add.....

If interpolation for RPG was to come to fruition, I like Scott's suggestion of ${var_name}.
Primarily because the syntax is already used in GoAnywhere which I use extensively.

Or, maybe it could be a function (overloaded?) like %interpolate(MyVar) with options for numerics as in %dec().

I understand the thought behind this but you're asking the next programmer to decipher a completely foreign (to them) syntax.
I do, however, use a named constant (QT) for quotes like yours, but I think that's pretty mainstream.

I really don't understand the difficulty being expressed over concatenation.

dcl-s MyVar char(10);

MyVar = 'Some Value';
MyString = 'This is a string with '
+ MyVar
+ ' concatenated in';

You can use %editc() for numerics.

Maybe not as clean but works fine. I build all SQL strings using %ScanRpl.

dcl-c QUOTE '''';
dcl-c PLUS '+';

SqlStmt = 'Select ~Q~P~Q~, 1 ~P~ 2 +
from FileA';
SqlStmt = %ScanRpl('~Q~':QUOTE:SqlStmt);
SqlStmt = %ScanRpl('~P~':PLUS:SqlStmt
Select 'P', 1 + 2 From Filea

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")
