Calling a Func from within a Func

5 posts in this topic

#1 ·  Posted (edited)

Hi guys...I'm a bit stuck on this one...What is the correct command to call a Func from within a func, but at the same time EXIT the current Func?

ie I want to jump from Func 1 to Func 2, and then back to func 1 without creating an endless f-up.

I know in assembler we use Ret or RetF and THEN cal a func :D

There are a few ways of doing it depending on the Return values of the functions but they will usually require a conditional.

$Rtn = _Function1()
If NOT @Error Then MsgBox(0, "TEST RESULTS", "Today is the 26th")

Func _Function1()
    If _Function2() Then Return SetError(0, 0)
    Return SetError(1,1)
EndFunc

Func _Function2()
    If @MDAY = 26 Then Return @MDAY
    Return False
EndFunc

Robin,

You cannot quit the first function BEFORE calling the second, but you can AFTER by using Return.

I assume you are using some form of conditional (If, Select, Switch) to decide whether to run the second function. If so, then just use Return after the function call:

; call function 1
_Func_1()

Func _Func_1()

; function 1 code

If $var > 23  ; or some other decision code
    _Func_2() ; call function 2
    Return    ; You leave function 1 and return to the main script
EndIf

; more function 1 code that is not used if function 2 has been called

EndFunc

I hope that helps
