FUNCTIONS again - RandomiserUsr - 2021-02-27
If you compile the following code
FUNCTION A(text as STRING)
Print B("Test")
RETURN 0
END FUNCTION
FUNCTION C(text as STRING)
Print B("Test")
RETURN 0
END FUNCTION
FUNCTION B(text as STRING)
Print ("Test")
RETURN 0
END FUNCTION
you will get
inputmud.bas:137: error: 'B' is neither an array nor a function.
inputmud.bas:135: warning: [W150] Parameter 'text' is never used
inputmud.bas:144: warning: [W100] Using default implicit type 'float' for 'C'
inputmud.bas:144: error: 'B' is neither an array nor a function.
inputmud.bas:143: warning: [W150] Parameter 'text' is never used
inputmud.bas:149: warning: [W100] Using default implicit type 'float' for 'B'
inputmud.bas:148: warning: [W150] Parameter 'text' is never used
but moving function B above like below compiles okay
So I guess it's a TOP Down design where the functions in the same .BAS should be ordered
FUNCTION B(text as STRING)
Print ("Test")
RETURN 0
END FUNCTION
FUNCTION A(text as STRING)
Print B("Test")
RETURN 0
END FUNCTION
FUNCTION C(text as STRING)
Print B("Test")
RETURN 0
END FUNCTION
Great tool
Thanks

That is. If you want to reference a function before being declare, use DECLARE:

Palm Face moment!
I even read that earlier this week!
Sorry for the spam :-)
thanks again
