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!

NAME

       echo, noecho - enable/disable terminal echo

SYNOPSIS

       cc [ flag... ] file... -I /usr/xpg4/include  -L	/usr/xpg4/lib 
	-R  /usr/xpg4/lib  -lcurses  [ library... ]

       c89 [ flag... ] file... -lcurses [ library... ]

       int echo(void);

DESCRIPTION

       The  echo()  function enables Echo mode for the current screen. The noecho() function disables Echo mode for the current screen. Initially,
       curses software echo mode is enabled and hardware echo mode of the tty driver is disabled. The echo() and noecho() functions control  soft-
       ware echo only. Hardware echo must remain disabled for the duration of the application, else the behavior is undefined.

ERRORS

       No errors are defined.
