Shell command line arguments generally indicate many things, including numbers. That means that, when a program looks at a command line argument, it is looking at a text string -- a string of characters. It is up to the program to convert that string to a number if the program wants a number. Take a look and "Line input and conversion" for some clues about how to do that: https://www.complang.tuwien.ac.at/forth/gforth/Docs-html/Line-input-and-conversion.html#Line-input-and-conversion It seems to be about converting text from the keyboard, but the same principles should apply. The words >number , >float , s>number? , and s>unumber? are of particular interest. -- Joel Rees One of these days I'll get someone to pay me to design a language that combines the best of Forth and C. Then I'll be able to leap wide instruction sets with a single #ifdef, run faster than a speeding infinite loop with a #define, and stop all integer size bugs with my bare cast. http://defining-computers.blogspot.com/2017/06/reinventing-computers.html More of my delusions: http://reiisi.blogspot.com/2017/05/do-not-pay-modern-danegeld-ransomware.html http://reiisi.blogspot.jp/p/novels-i-am-writing.html
