> Several of my scripts are filters, designed to be used with pipes … I think you posted the source to your 'uniq' a while back. I have not only used it in pipes, but have used it again and again as an example (to friends that haven't grasped the power of ARexx) of an elegant solution to a non-trivial problem. However, I'm becoming disturbed by an (increasing?) number of programs that do not support piping and/or redirection of their console output. For example, from the libraries here on CIS, LZ 1.92 Archive/Extract Utility and AmigaZoo 2.1 Beta 3 91/08/01 both fall into that category. I have often found in useful to pipe and/or redirect an archive 'contents' listing. Considering LZ 1.92: >lz v foobar.lha | uniq ; for example just didn't work under DOS 1.3/WShell 1.2 (only the header got piped if I remember) but guarantees a crash and burn under DOS 2.0/WShell 2.0. With Zoo 2.1: >zoo l foobar.zoo > foo.bar ; for example you often only get a partial list (apparently the final buffer doesn't get flushed). Of course, in all fairness, these problems may well be corrected in more mature versions of both programs which (I presume) are available from other sources. REC ——
