# Usage:
|
|
#
|
|
# From the shell:
|
|
#
|
|
# ./square
|
|
# cat file | ./square
|
|
# echo "123" | ./square
|
|
#
|
|
# Within calc:
|
|
#
|
|
# > read square
|
|
#
|
|
# With input from a terminal, there is no prompt but each non-empty
|
|
# line of input is evaluated as a calc expression and if it can be
|
|
# calculated, the square of the value of that expression is displayed.
|
|
# Execution stops when an empty line is input.
|
|
#
|
|
# From the shell:
|
|
#
|
|
# ./square
|
|
#
|
|
# The following shows lines of input followed by output:
|
|
#
|
|
# 1234
|
|
# 1522756
|
|
# ln(2)
