I use this code:-
/*===================================================================*/
Strip_Keyword_and_Option:
Procedure Expose keyword option
Parse Arg string
Parse Var string keyword temp "(" +0 string
option = ""
If (temp <> "" | string = "") Then Do
string = temp || string
End
Else Do
option = Substr(string, 2, Find_the_Match(1) -2, ")")
string = Substr(string, length(option) +3)
option = Strip(option)
End
If Left(keyword,1) = "," Then keyword = Substr(keyword,2)
Parse Var keyword keyword "=" temp
If Strip(temp) <> "" Then Do
If Pos(",",temp) > 0 Then Do
Parse Var temp temp "," trail
string = trail || "(" || option || ")" || string
End
option = temp
End
If Pos(",",keyword) > 0 Then Do
Parse Var keyword keyword "," temp
string = temp || "(" || option || ")" || string
Parse Var keyword keyword "=" option
End
Return string
Find_the_Match:
Procedure Expose string
Do i= Arg(1) +1 to Length(string)
If (Substr(string, i, 1) = "(") Then Do
i = Find_the_Match(i)
End
Else Do
If (Substr(string, i, 1) = ")") Then Do
Return i
End
End
End
Return i
