Did you know GB32 can do this?

[Roger Cabo]

I'm surprised after 30 years!


Dim a%%%%%%%%%%% = 1
Dim a%= 2

Msgbox a%%%%%%%%%%% & " " & a%

[webu]

Try this:

Dim a% = 1
Dim a%% = 2
Dim a%%% = 3
Dim a%%%% = 4

Print a%; a%%; a%%%; a%%%%      // -> 1 2 3 4


[Roger Cabo]

does this have any reason, or is there anything special to this, I don't know?

[webu]

I didn't know that either and was also surprised.

Ich wusste das auch nicht und war auch überrascht.

This is interesting as well:

Dim a%$ = 1
Print VarType(a%$)      // 255
Print TypeName(a%$)     // String
Dim a$% = 1
Print VarType(a$%)      // 3
Print TypeName(a$%)     // Integer
Dim a$a = 1
Print VarType(a$a)      // 3
Print TypeName(a$a)     // Integer (in a Variant)

It seems that GFABASIC only takes note of the last character of a variable name to see if it is a postfix; the rest it assumes is part of the variable name.

Very interesting.

Yes.. interesting and I never know before. This behavior seems to be much faster to recognize variables in terms of compiling code through the interpreter logic.

But anyway I have no problem with this.. and it works pretty well like all the other stuff in gb32. 👍☺️

From the Help Doc...

Declaring Variables
To declare a variable is to tell the program about it in advance. You declare a variable with the Dim statement, supplying a name for the variable:

Dim varname [As type] [= Value]

Variables declared with the Dim statement within a procedure exist only as long as the procedure is executing. When the procedure finishes, the value of the variable disappears. In addition, the value of a variable in a procedure is local to that procedure - that is, you can't access a variable in one procedure from another procedure. These characteristics allow you to use the same variable names in different procedures without worrying about conflicts or accidental changes.

Names of variables, constants, procedures etc are made up of letters (as well as the umlauts and the accented characters), underscore _, and digits, but not at the beginning of a name.

An interesting table of Data Type information in the Help Doc under Data Types...

Frankly it seems a bit weird that it does this. I would think that using a variable TEST% several times throughout the program and then mistakenly typing TEST%% would be a tough bug to find. I suppose that I find it more of a problem because I like to use the AUTO command at the beginning of my code rather than declare all my variables. I am old school. I do at least remove the AUTO command and declare them all after I have complete the program.
