Using exit in For Loop - Is this acceptable
Hi Folks -

Here is a for loop I've created and I just wanted to see if this was okay practice:

Code:
for M in NAME1 NAME1 NAME3
do
    echo "Executing MaxL:" $M >>${_LOGFILE} 2>&1
    . ${_STARTMAXLPATH}startmaxl.sh ${_MAINPATH}${_MAXLPATH}$M.mxl 
    
    _RC=$?
    if [ $_RC -eq 0 ]
    then
        echo "$M : Successful" >>${_LOGFILE} 2>&1
        continue
    fi
        echo "Encountered Error in MaxL: $M" >>${_LOGFILE} 2>&1
        echo "Exiting Shell Session" >>${_LOGFILE} 2>&1
        echo  | mail -s "Encountered Error in MaxL: $M" z@z.com
        exit
done

echo "${_SN} has completed with no errors" >>${_LOGFILE} 2>&1
exit

Essentially, I want to exit entirely if my NAME*.mxl script returns a failure code. Therefore, I've added an exit in that section. Is this okay?

Thanks!

excel::template::container::loop

Excel::Template::Container::Loop(3pm)			User Contributed Perl Documentation		     Excel::Template::Container::Loop(3pm)

NAME

       Excel::Template::Container::Loop - Excel::Template::Container::Loop

PURPOSE

       To provide looping

NODE NAME

       LOOP

INHERITANCE

       Excel::Template::Container

ATTRIBUTES

       o   NAME

	   This is the name of the loop. It's used to identify within the parameter set what variables to expose to the children nodes each
	   iteration.

CHILDREN

       None

EFFECTS

       None

DEPENDENCIES

       None

USAGE

	 <loop name="LOOPY">
	   ... Children here ...
	 </loop>

       In the above example, the children nodes would have access to the LOOPY array of hashes as parameters. Each iteration through the array
       would expose a different hash of parameters to the children.

       These loops work just like HTML::Template's loops. (I promise I'll give more info here!)

       There is one difference - I prefer using Perl-like scoping, so accessing of variables outside the LOOP scope from within is perfectly
       acceptable. You can also hide outside variables with inner values, if you desire, just like Perl.
