that's just my 2 cent's request for a future release of PB:
kinda
Procedure Func_with_opt_arg (arg1.l, arg2.s, Optional arg3.s="void")
If arg3 = "void" : MessageRequester ("Default", "Void", 1) : EndIf
; Blablabla
EndProcedure
That's all folks

I just pay a penny for this ... !
This would be useful in some cases to have this optional arguments made possible.
Especially for designing libraries or DLLs and even in regular software design in procedures.

I need optional parameters nearly everywere! Look at the command reference of Pure Basic - even Pure Basic itself uses optional parameters everywere!
I would love it!

Maybe easier:
Code: Select all
Procedure Func_with_opt_arg (arg1.l, arg2.s [, arg3.s])
If arg3 = "" : MessageRequester ("Default", "Void", 1) : EndIf
; Blablabla
EndProcedure

Einander, you don't understand what we want. For example: I want to create my own MsgBox command. With optional parameters I can write what I like:
Code: Select all
Msgbox("File doesn't exist")
Msgbox("Error","File doesn't exist")
Msgbox("Error","File doesn't exist",#RetryIgnore)
Msgbox("Error","File doesn't exist",#RetryIgnore,#IconAlert)
Msgbox("Error","File doesn't exist",#RetryIgnore,#IconAlert,#Systemmodal)
THAT IS COMFORT!
With your 'trick' I must write
Code: Select all
Global P.MsgboxStructure
P.title="Error"
P.text="File doesn't exist"
(...)
Msgbox(@P)
OK, that works (if you code it correctly
), but isn't nearly as comfortable as true optional parameters.
