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.
