This is a special symbol4I meaning the current file (the TEST.DIR file). Only the device parti$ will be used (i.e. the disk).E II.What do you want.

We can insert a module in this file that contains the description.JDIX will look in the DIX_DES.TLB file whenever a file is8 opened and see if-there is a description that matches the file.8DIX will match the filename with the name of the module.DThe module name may contain a full filespec with wildcards. DIX willMmatch the device,directory,name,type and version. Parts not in the MODULENAMENalways match. So if we give the module the name ".DIR", this module will matchall directory files.To include the file use the5$LIBRARY/INSERT DIX_DES.TLB DIRECTORY.DES/NAME=".DIR"JIf you do not have write access to the D9IX_DES.TLB file you can also use a8private .TLB file, see the HELP of DIX for more details.9After inserting the DIRECTORY.DES file in the .TLB file, :and you start DIX without the /DESCRIPTION qualifier, DIX 2will find the .DIR entry and display the following $DIX TEXT.DIR#SC:LAST#VI:RBW#CU:4,22HFile :SYS$SYSDEVICE:[STUBBE.PROGRAMS.DIX]TEST.DIR;1 Var/SeqARecsiz:32 Offs:0 Data:Norm Recnr:1 RFa:(1,0)9Des file :DSA0:[STUBBE.PROGRAMS.DIX]DIX_DES.TLB;13:8(.DIR)#VI: 0|VERSIONLIMIT |NOLIMIT 2|FLAGS |0 3|FILENAME |COMPARE.DIX16|COUPLE(1).VERSION|6!18|COUPLE(1).FILEID>|(26091,10,0)24|COUPLE(2).VERSION|5 26|COUPLE(2).FILEID>|(13784,7,0) #DV:4,3,10#DV:3,21,10#Note that headerline 3 changed from<Des file :SYS$SYSDEVICE:[STUBBE.PROGRAMS.DIX]DIRECTORY.DES;5to9Des file :DSA0:[STUBBE.PROGRAMS.DIX]DIX_DES.TLB;138(.DIR)AThe last display means the ".DIR" module of the DIX_DES.TLB file.This is the last scr;eenww<....Ø....... 0000018D 000 000 000 023 035 055 -..... 0000024 , This is an example of a Octal byte display6 You can use the following keys to change the display#KEY:KEY_DISPL_HEX:SCREEN_HBU1 #KEY_DISPL_HEX to change the mode to Byte Hex#KEY:KEY_DISPL_BIN:SCREEN_BBU4 #KEY_DISPL_BIN to change the mode to Byte Binary#KEY:KEY_DISPL_DEC:SCREEN_DBU5 #KEY_DISPL_DEC to change the mode to Byte Decimal#KEY:KEY_LONG:SCREEN_OLU2 #KEY_LONG to c=hange the mode to Longword Octal#KEY:KEY_WORD:SCREEN_OWU. #KEY_WORD to change the mode to Word Octal#SC:SCREEN_BLU#VI:BRW HFile :USER50:[STUBBF.PROGRAMS.DIX]TEST.DIR;1 Var/SeqARecsiz:42 Offs:0 Data:BINARYRecnr:1 RFA:(1,0)#CU:4,32% 3 2 1 0 0123#VI:-00000101000000000111111111111111 .... 0000000-01001111010000110010111001000001 A.CO 0000004-00000000000001010000000001001101 M... 0000008-000000000011000100011100111101>10 ö.1. 000000C-00000000000001000000000000000000 .... 0000010-00000000000101100001110011110001 ñ... 0000014-00000000000000110000000000000000 .... 0000018-00000000000010000001101111011000 Ø... 000001C-00000000000000100000000000000000 .... 0000020-00000000000100110001110100101101 -... 0000024-00000000000000000000000000000000 .. 0000028 1 This is an example of a Binary longword display6 You can use the following keys to change the display#KEY:KEY_DISPL_HEX:SCREEN_HLU5 ? #KEY_DISPL_HEX to change the mode to Longword Hex#KEY:KEY_DISPL_OCT:SCREEN_OLU7 #KEY_DISPL_OCT to change the mode to Longword Octal#KEY:KEY_DISPL_DEC:SCREEN_DLU9 #KEY_DISPL_DEC to change the mode to Longword Decimal#KEY:KEY_WORD:SCREEN_BWU/ #KEY_WORD to change the mode to Word Binary#KEY:KEY_BYTE:SCREEN_BBU/ #KEY_BYTE to change the mode to Byte Binary#SC:SCREEN_BWU#VI:BRW HFile :USER50:[STUBBF.PROGRAMS.DIX]TEST.DIR;1 Var/SeqARecsiz:42 Offs@:0 Data:BINARYRecnr:1 RFA:(1,0)#CU:4,33& 3 2 1 0 0123#VI:.0000010100000000 0111111111111111 .... 0000000.0100111101000011 0010111001000001 A.CO 0000004.0000000000000101 0000000001001101 M... 0000008.0000000000110001 0001110011110110 ö.1. 000000C.0000000000000100 0000000000000000 .... 0000010.0000000000010110 0001110011110001 ñ... 0000014.0000000000000011 0000000000000000 .... 0000018.0000000000001000 0001101111011000 Ø... 000001C.0000000000000010A 0000000000000000 .... 0000020.0000000000010011 0001110100101101 -... 0000024. 0000000000000000 .. 0000028 .
