- view - read-only text display program
-
- Usage: view textfile
-
- View is a simple program to let you scroll back and forth thru a text
- file and search for strings. It requires NANSI.SYS or equivalent to
- be loaded in CONFIG.SYS.
-
- It understands the following commands, which were chosen to make users
- of the Unix text editor 'vi' comfortable:
- q quit
- / search forward
- ? search backwards
- n find next
- N find next in opposite direction
- j or arrow move down
- k or arrow move up
- h or arrow move left
- l or arrow move right
- ^F or PageDown move one page down
- ^B or PageUp move one page up
- It expands tabs on 8 column boundaries.
-
- Technical details:
- It was written in 1985 in 8086 assembly language, and uses MS-DOS function
- calls for all input and output (no direct writing to video screen). Because
- it batches its output, screen updates are nearly instantaneous when used with
- NANSI.SYS. View.com uses VT100 style insert and delete line sequences to
- avoid repainting the whole screen when scrolling by just one line.

- is available at universities and research institutions. Many
- commercial e-mail systems such as Compuserve have gateways that allow
- you to send e-mail to Internet addresses.)
