- .SH NAME
- foreach \- Iterate over all elements in a list
- .SH SYNOPSIS
- \fBforeach \fIvarname list body\fR
- .BE
-
- .SH DESCRIPTION
- .PP
- In this command \fIvarname\fR is the name of a variable, \fIlist\fR
- is a list of values to assign to \fIvarname\fR, and \fIbody\fR is a
- Tcl script.
- For each element of \fIlist\fR (in order
- from left to right), \fBforeach\fR assigns the contents of the
- field to \fIvarname\fR as if the \fBlindex\fR command had been used
- to extract the field, then calls the Tcl interpreter to execute
- \fIbody\fR. The \fBbreak\fR and \fBcontinue\fR statements may be
- invoked inside \fIbody\fR, with the same effect as in the \fBfor\fR
- command. \fBForeach\fR returns an empty string.
