This command, a part of [tclx] is documented thusly within the package: : '''ctoken''' ''strvar separators'' Parse a token out of a character string. The string to parse is contained in the variable named ''strvar''. The string ''separators'' contains all of the valid separator characters for tokens in the string. All leading separators are skipped and the first token is returned. The variable ''strvar'' will be modified to contain the remainder of the string following the token. This command does not work with binary data. Compare with [split] and note that they are ''not'' equivalent. ---- Can anyone provide me an example of how this works? 50 % set s abc-def=ghi/jkl:mno(pqr)stu&vwx@yz abc-def=ghi/jkl:mno(pqr)stu&vwx@yz 51 % set sep -:()@ -:()@ 52 % ctoken s $sep abc 53 % set s -def=ghi/jkl:mno(pqr)stu&vwx@yz 54 % ctoken s $sep def=ghi/jkl 55 % set s :mno(pqr)stu&vwx@yz 56 % ctoken s $sep mno 57 % set s (pqr)stu&vwx@yz 58 % ctoken s $sep pqr 59 % set s )stu&vwx@yz 60 % ctoken s $sep stu&vwx 61 % set s @yz 62 % ctoken s $sep yz 63 % set s 64 % ctoken s $sep <> Command | TclX
