Network Support Systems Division 54 Regional Drive Concord, New Hampshire 03301 (603) 224-6511 X2529 Program: VTL Author: Robin Miller Date: Fall 1985 Description: This program is used to list file(s) on a VT100 family terminal. The file(s) are displayed one screen at a time for easy viewing. Various commands can be entered to change listing parameters or to position to a particular portion of the file. Many of the commands are the same as the Digital editor EDT. Commands can be entered either by using keys on the VT100 keypad, or by entering commands to the prompt at the bottom of the screen. Some of the major features of the program are outlined below: o CTRL/C detection for aborting searches, etc. o Delete the file being displayed. o Display a ruler along the top of the file. o Display the next file or next the directory. o Display record numbers along the left margin. o Display the file header of file being displayed. o Print the file being displayed. o Search (forward only) for a specified string. o Shift the display window left or right. o Split screen mode to display two files. o Teco compatible see-all mode. o Write portions of the file being displayed. The maximum record size that can be displayed is 512 characters. All commands have a repetition count of one. Relative and indexed files are not supported. The special wildcard characters "* and %" can be used with VTL on RSX-11M using FCS for I/O instead of RMS. Previously these were only valid on VMS since a native image was being called to lookup files. The Digital files ASCR50.MAC and PARSFN.MAC were modifed to allow this type of wildcard lookup. Unfortunatly, since they are Digital source files I can't submit them to the SIG Tape. I hope to submit an article on this to the RSX News Letter in the near future. These modified modules are in the object library (VTL.OLB) and can be extracted an used with other programs. Refer to module VTLOPE for further information on using these (must save the file name block). [ File "VTL.DOC" contains full documentation for this program. ] ------------------------------------------------------------------------------ Fall 1985 DECUS Submission. This version of VTL has several bug fixes and will now sense the AVO setting of the terminal characteristics. Previously, either the /AVO qualifier had to be specified, or a taskbuild option changed to let VTL know the terminal was equiped with the Advanced Video Option.
