/* $VER: LZXDir.dopus5 1.1 tINIC/mAXIMUM (26.6.95) - This version by Stone-D Copyright © 1995 by Edmund Vermeulen This version by Stone-D (Laga Hale) Modified to co-exist with lha version of same file also modified by Stone-D. Placed in the public domain. No restrictions on distribution or usage. Usage differences with original : The original required you to change the lister buttons to link to the actual arexx script. Not so with this one. Change, for example, the COPY button from AREXX DOpus5:Rexx/LzxDir.dopus5 {Qp} back to the COMMAND COPY. Do the same with MOVE, and DELETE. EMail Stone-D at the following address : stone-d@eldar.demon.co.uk To make LzxDir.dopus5 open it's own listview, refer to line 165 ARexx script for Directory Opus 5 to show the contents of an Lzx archive in an Opus lister and operate on the files and directories inside the archive as if it is a normal directory, whilst allowing simultaneous access to similiar scripts...such as the lzxdir.dopus5 one. */ ver='$VER: LZXDir.dopus5 1.1 tINIC/mAXIMUM (26.6.95) - This version by Stone-D' /* for compiled version */ signal on syntax /* intercept syntax errors */ options results /* need results */ options failat 21 /* external commands are allowed return code 20 */ numeric digits 10 /* needed for convertdate routine */ lf='0a'x /* ascii code for linefeed */ if ~show('l','rexxsupport.library') then call addlib('rexxsupport.library',0,-30) /* needed for delay() */ /* init locale */ ok=show(l,'locale.library') if ~ok then ok=addlib('locale.library',0,-30) if ok then catalog=opencatalog('LZXDir.catalog','english',0) parse arg cmd portname handle .
