. data-file    # Load a data file.
# Same effect as "source data-file", but more portable.

#  The file "data-file" must be present in current working directory,
#+ since it is referred to by its 'basename'.

# Now, reference some data from that file.

echo "variable1 (from data-file) = $variable1"
echo "variable3 (from data-file) = $variable3"

let "sum = $variable2 + $variable4"
echo "Sum of variable2 + variable4 (from data-file) = $sum"
echo "message1 (from data-file) is \"$message1\""
# Note:                            escaped quotes
