The following UNIX Shell statements and constructs have no equivalent with the
commands built into menu;
wait umask
trap shift
readonly until
read case
break continue
IFS=
&& ||
${argument:-value} ${argument:=value
}
${argument:?value} ${argument:+value
}
Also, the UNIX shell quotes special characters with the backslash (\). The quote character must be set in menufiles as follows:
set QUOTEC to "\\"
