Determining if variable or static string is passed to a Sub

[TempodiBasic]

Hi Dano

Code: (Select All)

Dim GlobalString$, GlobalFixedString$7



GlobalString$ = "123456789012345"

GlobalFixedString$7 = "1234567890"

Print "Global variable", "In function variable" + "  Kind 0=fixed/ -1=variable"

Print GlobalString$, WhatKindOfString%(GlobalString$)

Print GlobalFixedString$7, , WhatKindOfString%(GlobalFixedString$7)

End



Function WhatKindOfString% (FunctionString$5)

    '-1 = Fixed lenght, 0 = variable lenght

    Print FunctionString$5, ;

    If Len(FunctionString$5) > 7 Then WhatKindOfString% = -1 Else WhatKindOfString% = 0

End Function

here screenshot that confirms affirmations of Bplus

I dunno if compiler must control this kind of data type with distinguish between fixed string and string.
In the same manner if you declare into the Function a SHARED variable, the compiler doesn't test if there is a same variable into main, but I dunno if this is a must for the compile... surely you can bypass this problem using Option _explicit at top of your code.



So for now you cannot have this information directly from parameters of function!

Please say me:
I have 2 question for you:
 1. if it is difficult to add a parameter to the SUB/FUNCTION , is it difficult too to add a SHARED variable into it?
2. what is the goal to distinguish between Fixed and Variable lenght ?
