.SH NAME
|
||
|
|
continue \- Skip to the next iteration of a loop
|
||
|
|
.SH SYNOPSIS
|
||
|
|
\fBcontinue\fR
|
||
|
|
.BE
|
||
|
|
.SH DESCRIPTION
|
||
|
|
.PP
|
||
|
|
This command is typically invoked inside the body of a looping command
|
||
|
|
such as \fBfor\fR or \fBforeach\fR or \fBwhile\fR.
|
||
|
|
It returns a 4 (\fBTCL_CONTINUE\fR) result code, which causes a continue
|
||
|
|
exception to occur.
|
||
|
|
The exception causes the current script to be aborted
|
||
|
|
out to the innermost containing loop command, which then
|
||
|
|
continues with the next iteration of the loop.
|
||
|
|
Catch exceptions are also handled in a few other situations, such
|
||
|
|
as the \fBcatch\fR command and the outermost scripts of procedure
|
||
|
|
bodies.
|
||
|
