- HOW TO USE BROWSE.COM
-
- BROWSE.COM lets you do what the DOS TYPE command doesn't:
- move forward and backward within a display file, line by line
- or screen by screen.
-
- The author of this utility program is Charles Petzold, a
- contributing editor of PC Magazine. The ASSEMBLY and BASIC
- source codes to make BROWSE.COM appeared in the March 25, 1986,
- Volume 5, Number 6 issue of PC Magazine.
-
- BROWSE writes directly to the display, so it's fast, and it
- uses the cursor keys to navigate within the file, line by
- line, screen by screen, backward and forward, left and right.
-
- BROWSE is easy to use. Just enter A>BROWSE filename
-
- Since BROWSE requires DOS 2.0 or later, you can use a drive
- and path specification before the filename.
-
- When you invoke BROWSE, it save the current screen contents and
- displays the first 25 lines of the file. To see the next 25
- lines, press PGDN. To go backward 25 lines, press PGUP. To go
- ahead or back one line at a time, use the Cursor Up and Cursor
- Down keys. The Home keys brings you back to the top of the file.
- The End key displays the last line of the file on the screen.
-
- For lines longer than 80 columns, BROWSE does not word wrap the
- rest of the line on the display but truncates the line at the
- right of the display instead. If you want to see the rest of
- the line, you scroll the display horizontally by pressing the
- Cursor Right key. Each time you press the Cursor Right key the
- display window moves eight characters to the right. The Cursor
- Left key brings the display window back to normal.
-
- To get out of BROWSE, simply press the ESC key or CTRL-BREAK.
- Your previous screen will be restored, and you'll be back at
- the DOS command level.
-
- BROWSE has the following four error messages:
- "Requires DOS 2.0 or above" will appear if you try to run the
- program under DOS 1.1.
- "Not enough memory." BROWSE requires about 33K to run.
- "File not found." BROWSE could not find the file.
- "Unsupported video mode." BROWSE writes directly to the screen,
- so it prints this message if the screen happens to be in a
- graphics mode.

- page 253 of the above mentioned issue of PC Magazine.

- and enter the following command:
