.SH NAME
split \- Split a string into a proper Tcl list
.SH SYNOPSIS
\fBsplit \fIstring \fR?\fIsplitChars\fR?
.BE
.SH DESCRIPTION
.PP
Returns a list created by splitting \fIstring\fR at each character
that is in the \fIsplitChars\fR argument.
Each element of the result list will consist of the
characters from \fIstring\fR that lie between instances of the
characters in \fIsplitChars\fR.
Empty list elements will be generated if \fIstring\fR contains
adjacent characters in \fIsplitChars\fR, or if the first or last
character of \fIstring\fR is in \fIsplitChars\fR.
If \fIsplitChars\fR is an empty string then each character of
\fIstring\fR becomes a separate element of the result list.
\fISplitChars\fR defaults to the standard white-space characters.
For example,
.CS
\fBsplit "comp.unix.misc" .\fR
.CE
returns \fB"comp unix misc"\fR and
.CS
\fBsplit "Hello world" {}\fR
.CE
returns \fB"H e l l o { } w o r l d"\fR.
