Shared coding conventions allow teams to collaborate effectively. Typing operation codes, keywords, specification codes, compiler directives and
built-in functions in upper case makes them more immediately recognizable as such, thereby making the code easier to read.
Noncompliant code example
c test12 plist
c parm asdf01
c parm asdf02
c parm @pdq
/free
if x = *blank;
read a;
endif;
/end-free
