- Restrictions:
- All positioning is relative to the current block in
- storage. The size of the block depends on the amount of
- memory available, up to 64K.
-
- The maximum record length currently allowed is 255.
-
- Logical records (ending in LF and/or CR) are placed
- into the DOS screen buffer - mono or color display.
-
- PC-DOS Version 2.0 or later is required.
-
- ANSI.SYS is NOT required.
-
- Scanning for text:
- To scan for a character string, type a slash (/)
- followed by one or more (up to 32) characters. The
- scan text, but not the slash, is displayed on the
- command line. Only the current block is scanned.
-
- If the text is found, the line containing it is displayed
- as a blinking line.
-
- If the text is NOT found, an error message is displayed
- and the display remains unchanged. To scan the next block,
- "page" into it with PgDn or Down, and use F3 to re-scan.
-
- Screen attributes:
- There are three classes of attributes used. One for
- normal display lines - lines 2 to 24, another for
- special lines - lines 1 and 25, and a third for the
- background color.
-
- These attributes may be changed by using DEBUG:
-
- at offset 11C = 09 ;special lines, hi-lighted or lt.blue
- at offset 11D = 02 ;normal lines, green
- at offset 11E = 00 ;background, black
-
- If these values don't match, you have a different version.
