If succinctness is the criterion, shouldn't everyone be using APL instead of COBOL?
Python is not as succinct as it might be. My understanding is that Python uses AND and OR rather than the more common & and | or && and ||. Up to two more keystrokes each! Is that a bad thing? For any language I suspect it is easy for an aficionado to pick a task for which the language is particularly well suited. "99 Bottles of Beer" is more concise in C++ than in Python, and MUCH more concise in BASIC. Does that make BASIC a better language? https://en.wikipedia.org/wiki/99_Bottles_of_Beer Charles -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of David Crayford Sent: Wednesday, June 29, 2022 2:24 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: Some questions on SYSCALL On 30/06/2022 4:22 am, Bernd Oppolzer wrote: >> > This is an old OS/2 REXX program (from the 1990s, IIRC), > used to traverse a directory tree recursively and issue a command in > every subdirectory found: > > > /* rexx */ > > arg command > > call RxFuncAdd "SysLoadFuncs", "REXXUTIL", "SysLoadFuncs" > call SysLoadFuncs > > dir = directory() > if right(dir,1) = "\" then > dir = left(dir, length(dir) - 1) > > call tree dir, command > > x = directory(dir) > > exit > > > tree: procedure > > arg dir, command > > say "*** Verzeichnis in Bearbeitung: "dir" ***" > > x = directory(dir) > > command > > rc = SysFileTree("*.*", verz, "D") > do i = 1 to verz.0 > dir = word(verz.i, 5) > call tree dir, command > end > > return > > > you may notice the recursive call of the procedure "tree". > > I don't see any justification for your REXX bashing; > it's just another flavor of scripting language, which allows to do > great things, > once you manage to use it. Sorry Brend, but I don't consider that snippet to be great! It's a perfect example of flabby, verbose REXX code. The only justification for using REXX is that you personally favor the language. Python is far more succinct. |for| |root, dirs, files ||in| |os.walk(path_of_the_directory):| |||for| |i ||in| |files:| |||print||(os.path.join(root, i))| ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
