are constants type declaration case sensitive in HLASM?

Question

Is there a difference for using lower or uppercase C when declaring a constant char ?

FIELD1       DCL      C'1'
FIELD2       DCL      c'1'

Code runs as if it made no difference, but I see no mention of it in the documentation.

Answer 1

Nope, HLASM is case-insensitive. You can, of course, have mixed-case literal strings (e.g., C'Hello world'), but labels (e.g., Field and FIELD1) and keywords (e.g. DCL and dcl) are not case-sensitive.
