Description
This is a re-written version of the String Sort function. This has a new part to it which is not in the previous function (String Sort 1). Note: Words are referred to as 'chunks'
Usage
Push 4 ; get text after 4th chunk from string end Push 2 ; get 2 chunks before the 4th Push "Hello all, I am Afrow UK!!!" ; input string Call AdvStrSort Pop $R0
$R0 will now be: "I am"
Note: You can also Push higher chunk counts than there actually are in the string, and nothing will go wrong or be affected.
Usage 2
Push 10 ; get text after 10th chunk from string end Push 2 ; get 2 chunks before the 10th Push "$R1" ; input string (unknown string, but has spaces) Call AdvStrSort Pop $R0
$R0 will now be the first two chunks of the string, even though there could have been only 5 chunks in the unknown string.
The Function
Function AdvStrSort Exch $0 ; input string Exch Exch $1 ; count to get part Exch Exch 2 Exch $2 ; get ammount of chunks from end Exch 2 Push $3 Push $4 Push $5 Push $6 Push $7 StrCpy $0 " $0" StrCpy $3 0 StrCpy $4 0 loop: IntOp $3 $3 - 1 StrCpy $6 $0 1 $3 StrCmp $6 "" skip StrCmp $6 " " roger ; to change chunk seperators, edit this (" ") Goto loop roger: StrCpy $7 $0 "" $3 IntOp $4 $4 + 1 StrCmp $4 $2 0 loop StrCmp $1 $2 0 +3 StrCpy $0 $7 Goto end skip: StrCpy $4 0 StrLen $5 $7 top: IntOp $4 $4 + 1 loop2: IntOp $5 $5 - 1 StrCpy $3 $7 1 -$5 StrCmp $3 "" end StrCmp $3 " " 0 loop2 ; to change chunk seperators, edit this too (" ") StrCmp $4 $1 0 top StrCpy $0 $7 -$5 end: StrLen $1 $0 IntOp $1 $1 - 1 StrCpy $0 $0 $1 -$1 Pop $7 Pop $6 Pop $5 Pop $4 Pop $3 Pop $2 Pop $1 Exch $0 ; output string FunctionEnd
