Hi, some remarks about using forth: - certainly forth is missing all that nice pattern matching like awk or perl, all this has to be coded. - I assume that even arrays are not available in forth - because forth uses very unusual semantics (reverse polish notation) it is not easy to understand and to maintain (you have always to keep in mind, what is in this moment at which position on the stack).
