-
- Purpose Permits scrolling forward and backward
- throughout a file without use of a word
- processing program.
-
- Format: BROWSE [d:][path]filename[.ext] [/W]
-
- Remarks: The DOS TYPE command does not permit you to
- scroll ahead or go back to previously
- displayed material in a file. It also exits
- at the first instance of Ctrl-Z (ASCII 26,
- conventionally used as an End-of-File
- marker), making it impossible to scan binary
- (e.g. .COM) files for error messages,
- copyright notices, and the like.
-
- BROWSE.COM overcomes these shortcomings,
- giving you the chance to go immediately to
- the top or to the end of a file (the Home and
- End keys, respectively), to the succeeding or
- previous screen (PgUp and PgDn), or to move
- up or down a line at a time (Up Arrow or Down
- Arrow). To return to DOS, simply press the
- Escape key or Ctrl-Break.
-
- Wide displays, e.g. a spreadsheet file, are
- not broken at 80 columns, as with TYPE.
- BROWSE ignores carriage returns (ASCII 13),
- breaking lines only on line feeds (ASCII 10).
- The Right Arrow key scrolls the display to
- the right in eight-character increments (see
- Note 3 below) to view wide displays; the Left
- Arrow key returns you immediately to column
- zero.
-
- BROWSE expands tab characters (ASCII 9) to
- the next eight-character boundary, but does
- no other character processing unless the /W
- parameter is specified. Use of the /W option
- permits using BROWSE with WordStar files.
-
- Notes:
-
- 1. BROWSE can run under TopView or Windows;
- specify "writes directly to screen" in
- the .PIF and use the default 52K memory
- requirement. (The program actually
- requires only approximately 33K to run.)
- For the TopView PIF, specify that the
- program intercepts Interrupt 23h.
-
- 2. BROWSE is compatible with the IBM
- monochrome, CGA, and EGA displays, and
- will even run in the EGA 43-line mode.
- Files prepared with word-processors that
- employ a one-line-per-paragraph format
- (such as Microsoft Word and XyWrite) may
- to require excessive right scrolling,
- however.
-
- 3. BROWSE.COM can be patched with DEBUG so
- that its right-scroll jumps by more than
- the default eight characters. The
- address to patch is 10F in the .COM
- file. After entering DEBUG BROWSE.COM
- type
-
- E 10F
-
- and the default value (08h) will appear.
- Type the desired hexadecimal number (28
- for a 40-column increment; 50 for an 80-
- column increment) and press <Enter>.
- Then type W<Enter> to write to the disk
- and Q<Enter> to quit DEBUG.
-
- 4. Requires DOS 2.0 or later.
