The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
Justin,
This proposed feature might work okay in any interpreted language like AWK, PHP, Python, PERL, or Javascript, etc., but would be difficult to impossible to implement this in compiled languages like ILE RPG IV, or ILE COBOL or ILE C/C++ or ILE CL.
To do so would require that the runtime routines, (e.g. "printf" in the example), would need to be able to access the symbol table of the compiled program. The symbol table is normally only available at "compile time" unless you compile with "debug" enabled. To access the debug symbol table would require running the program "in debug mode." :-/
I think it would require a huge effort to implement this, for relatively little real benefit.

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")
