'::: PROGRAM: ULIST.BAS :::
'::: AUTHOR: Mike Shaffer :::
'::: DATE: Feb 2, 1991 :::
'::: VERSION: 2.1 :::
'::: PURPOSE: Shows a userlist on Novell with total :::
'::: elapsed time logged-in. :::
'::: REVISIONS: Feb 6, 1991: Improved structure of source :::
'::: for general release (V2.0-2.1) :::
'::: :::
'::: :::
'::: NOTES: This program assumes you're using PDQ from :::
'::: Crescent Software. If not (shame on you!) :::
'::: than you can modify the interrupt call to :::
'::: use INT86 as provided with QuickBASIC, and :::
'::: take out the reference to PDQDECL.BAS. :::
'::: Also change: PDQVALx() references to VAL() :::
'::: PDQCPRINT references to PRINT :::
'::: :::
'::: Compile using: :::
'::: :::
'::: BC ulist/o/s; :::
'::: LINK /NOD/NOE ulist,,,pdq[386].lib :::
'::: :::
'::: or similar... :::
'::: :::
'::: :::

'::: Author is not responsible for any damages resulting from use :::
'::: or inability to use this program. The entire responsibility :::
'::: for use of this program is with the user. :::
