/*
* 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)
* ~.48045301391820142467
* config("mode","frac"), bernoulli(10)
* 25/4356
* config("mode", "hex"), 0xff
* 0xfe01
