Nonsense, Ascii was removed to reduce the administrative overhead for the Pb team.

At least nice to see that my point of view is shared.

THX nco2k

for GOSUB - it think it should be really removed, because procedures can do everything, that gosub can do, but i a better, easier way.

But Goto - goto is like an ejection seat. Don't use it every time, only on emergencys

There a reason, why, for example, a goto to a diffrent procedure is imposible. An Goto to a pointer can easlier cause very hard to detect errors. Also a jump outside a structure can theoretically cause really bad things.

Can you post a example-Code, where you need "Goto" on pointers? Maybe there is a simpler better Method to solve your problem.

well the particular one that made me post the request was because i had to use inline assembly for a jmp into my jump table, a Goto would've been ideal and then i wouldn't need two CompilerIf/ElseIfs to handle jmp dword/qword for x86/64 http://purebasic.fr/english/viewtopic.php?f=12&t=67044

Or Here

ok, thats a very spezific problem

on C64-Basic there was a "on xx goto label1,label2,label3,label4..." - maybe this would be nice in PB.

But in your case maybe a Macro should be a good solution: Macro is incomplete, because i don't know the command to access the protected variable

I remember the On x GOTO 100,200,300 command.
But in Purebasic we have Procedures.
Why not a SELECT instead? Should be easier to maintain.

But I'm not willing to to create some hundred procedures

Code: Select all

SELECT a
 case 0
 Procedure_1()
 case 1
 Procedure_2()
 case 3
 Procedure_3()
 default
 Procedure_1()
 Endselect 

Should be easier to maintain.

Always smoking a cigarette while the processor is calculating, wouldn't good for my health

Macro GotoVariable(Variable)
;   CompilerIf #PB_Compiler_Procedure=""
    CompilerIf #PB_Processor_x64
      ! jmp qword [v_#variable]

      ! jmp dword [v_#variable]
    CompilerEndIf
   CompilerElse
     ;Sorry don't know how to access a protected Variable in Asm here....
   CompilerEndIf
EndMacro

But that's just a wrapper for the jmp instruction i'm already having to use, using the two CompilerIf/Else directives i mentioned it'd be good not to have to type ... another good example of why Goto <Address> would be better
