Case Sensitivity
The names of user defined macros, subMacros, variables and keywords such as MESSAGE, CREATE LINE, WHILE, etc. are case-insensitive. These lines are equivalent:
#example 1:
MESSAGE "hello, world"
MESSAGE "hello, world"
MESSAGE "hello, world"
#######################
#example 2:
DEFINE out AS string
DEFINE OUT AS string
Only string constants are case-sensitive:
#CORRECT:
Save "C:\temp\output.com" "CGM"
#INCORRECT:
Save "C:\temp\output.com" "cgm"
