- Jeff Prosise
- 1988 No. 21 (Utilities)
-
-
- Purpose: A memory-resident utility that automatically maintains a record
- of computer activity suitable for tax records, client billings, and use-
- analysis.
-
- Format: LOG [filespec] [/U]
-
- Remarks: Entered without the optional filespec parameter, LOG opens a
- file named USAGE.LOG in the root directory of the current drive. The user may
- over-ride any or all of the drive, path, and filename defaults by supplying his
- desired parameters as the filespec option when LOG is initially run. Although
- it can be executed from the DOS prompt, LOG is normally loaded by being included
- as a line in an AUTOEXEC.BAT file. Provided it is either the only or the last
- memory-resident program loaded, LOG can be uninstalled by executing the command
- with the /U parameter.
-
- After listing the date, LOG files provide a single-line columnar display
- of start, end, and elapsed times for each program run. The program name and any
- parameters entered with it are also logged, as is the "level" of DOS activity.
- The original DOS level is 0; a program running under DOS is level 1; invoking a
- secondary copy of COMMAND.COM by shelling out from the program to DOS,
- represents level 2, etc. LOG can track up to 10 levels of DOS activity. Time
- spent at the DOS prompt is identified as <idle>. LOG does not record the use of
- internal DOS commands (DIR, CD, REN, for example), nor command calls that fail
- ("Bad command or filename"). LOG produces pure ASCII files that can be TYPE'd
- to the screen or to a printer and that can be used with a browse utility or text
- editor.
-
- Available for downloading from PC MagNet (see the LOG by Modem sidebar),
- LOG.COM is already compiled and ready to run. LOG.BAS will automatically create
- LOG.COM when run once in BASIC. To create LOG.COM from the LOG.ASM source code
- requires use of a macro assembler (IBM or Microsoft, Version 2 or later) and the
- following commands:
-
- MASM LOG;
- LINK LOG;
- EXE2BIN LOG LOG.COM
