New Function

[Afrow UK]

Usage:
Push "My name is Afrow UK, and I love NSIS"
Push "4"
Call GetStringPart
Pop "$R0"
$R0 should now be "My name is Afrow UK," but it's not working.
I definatly had this script working before, and now it does not work at all.

code:


Function GetStringPart

  Pop $R4

  Exch $R0

  Push $R1

  Push $R2

  Push $R3

  StrCpy $R1 -1

  StrCpy $R3 0

  loop:

    StrCpy $R2 $R0 1 $R1

    StrCmp $R3 $R4 exit2

    StrCmp $R2 "" exit2

    StrCmp $R2 " " exit ; Change " " to "\" if ur inputting dir path str

    IntOp $R1 $R1 - 1

  Goto loop

  exit:

    StrCpy $R0 $R0 $R1

    IntOp $R3 $R3 + 1

    Goto loop

  exit2:

    Pop $R3

    Pop $R2

    Pop $R1

    Exch $R0

FunctionEnd

Basically, it will clear the string from the start up to the space specified.
Thats where the Push "4" comes in. It should reomve all of the string from the end up to the 4th space.

Can anyone see whats wrong with it?
