I second Don Cragun in his third expectation; that's why I asked how you called the script (which unfortunately you did not answer). It looks like your parent script scrambles character (set)s as the case statement evaluates and recognizes -OPT correctly but then obviously fails when providing the option values themselves.

Hello all,

Hello All,
I'm trying to parse through a file and display all the hidden characters, including all carriage and line returns. I usually use cat -v, but this doesn't display the carriage and line returns. Does anyone know how this can be done?
Thanks

catch
catch(n) Tcl Built-In Commands catch(n)
__________________________________________________________________________________________________________________________________________________
NAME
catch - Evaluate script and trap exceptional returns
SYNOPSIS
catch script ?varName?
_________________________________________________________________
DESCRIPTION
The catch command may be used to prevent errors from aborting command interpretation. Catch calls the Tcl interpreter recursively to exe-
cute script, and always returns without raising an error, regardless of any errors that might occur while executing script.
If script raises an error, catch will return a non-zero integer value corresponding to one of the exceptional return codes (see tcl.h for
the definitions of code values). If the varName argument is given, then the variable it names is set to the error message from interpret-
ing script.
If script does not raise an error, catch will return 0 (TCL_OK) and set the variable to the value returned from script.
Note that catch catches all exceptions, including those generated by break and continue as well as errors. The only errors that are not
caught are syntax errors found when the script is compiled. This is because the catch command only catches errors during runtime. When
the catch statement is compiled, the script is compiled as well and any syntax errors will generate a Tcl error.
EXAMPLES
The catch command may be used in an if to branch based on the success of a script.
if { [catch {open $someFile w} fid] } {
puts stderr "Could not open $someFile for writing
$fid"
exit 1
}
The catch command will not catch compiled syntax errors. The first time proc foo is called, the body will be compiled and a Tcl error will
be generated.
proc foo {} {
catch {expr {1 +- }}
}
