Hello. I am surprised why it isn't exists yet!
Code: Select all
EnableExplicit
#constant = 0
Define int.i = 1
Define string.s = "hello"
Dim arr.s(4)
string = "hi"
Like that:
Warning: constant "#constant" is assigned but never used!
Warning: variable "int" (Integer) is assigned but never used!
Warning: variable "arr" (String, Array) is assigned but never used!

Good idea for variables, but not for constans..
Think about the include files for libs etc. it would be annoying to see 2k 'Warning: constant "#constant" is assigned but never used!' messages.
Unsued constants could be execluded from the ASM output (if not done allready?) - to save memory

Constants are like macro replacements. This is the same:
Code: Select all
#CONSTANT = 12
Macro CONSTANT : 12 : EndMacro
Not used, nothing is included. Used, the value is inserted. (x = #CONSTANT and x = CONSTANT become both x = 12)
Other languages have const variables. Variables that are not write-able after assignment (you can read them and you can get a pointer to const variables).
This is not the same as PB constants.

Thank you Danilo for making that clear.

Would be nice, but may also come with an option to turn it off.

Yes, would be a nice feature. For me it would be enough, checked only when I start Compiler/SyntaxCheck
