Under what sh `scaley 27` is a numeric-parameter ?
Hi,
this part of code comes from an example
in dialog utility.
Running it under /sh
the following error is generated
"
Error: Expected a numeric-parameter for --begin.
Use --help to list options.
"
Is this example is 6 years old only, I expect it to work finally.

ROWS="`cut $tempfile -f1 -d, | cut -f2 -d:`"
COLS="`cut $tempfile -f2 -d,`"
rm $tempfile
# account for widest labels
COLS=`expr $COLS - 30`
# Takes an integer, multiplies it for COLS, divides for 132
scalex() {
echo $[$1*$COLS/132]
}
scaley() {
echo $[$1*$ROWS/60]
}
$DIALOG --backtitle "$TITLE" --no-shadow \
--begin `scaley 27` `scalex 98`
