Description
This is another simple string which outputs the 1st part of a string (before a specified character) and outputs the rest of the string (after the specified character)
Usage

Function SplitFirstStrPart Exch $R0 Exch Exch $R1 Push $R2 Push $R3 StrCpy $R3 $R1 StrLen $R1 $R0 IntOp $R1 $R1 + 1 loop: IntOp $R1 $R1 - 1 StrCpy $R2 $R0 1 -$R1 StrCmp $R1 0 exit0 StrCmp $R2 $R3 exit1 loop exit0: StrCpy $R1 "" Goto exit2 exit1: IntOp $R1 $R1 - 1 StrCmp $R1 0 0 +3 StrCpy $R2 "" Goto +2 StrCpy $R2 $R0 "" -$R1 IntOp $R1 $R1 + 1 StrCpy $R0 $R0 -$R1 StrCpy $R1 $R2 exit2: Pop $R3 Pop $R2 Exch $R1 ;rest Exch Exch $R0 ;first FunctionEnd
I used this script to get values from a multiline text box (by firstly replacing all " " with "|").
