I.DOC for I.COM V. 2, A Text File Utility Program 1/12/84
I.COM allows viewing of files of any length by filling memory with as
much of the file as will fit (about 55K max). The file, or portion of
a file, in memory may be scrolled through, paged forward or
backwards, searched, and skipped through in 124 line jumps. You can
jump to the first page or the last page and print any page. When you
are through with the current buffer contents, you can load the next
part of a large file or another file or you can quit with a warm boot.
To use I.COM you may enter the file name after the program name, i.e.
I B:LISTING.ASM or let the program prompt you for the file name. It
will then load the file into memory and display the first page.
Commands, all of which are single characters may then be entered.
The commands are:
SP - Print the next line to the console
V - Print the next page to the console
Z - Print the last page to the console
S - Search for a string, forward
C - Continue search for current string
P - Print the current page to LST device
N - Get a new file
M - Get the next part of a file
, - Skip back 124 lines
< - Skip back to the start
. - Skip forward 124 lines
> - Skip forward to the end
Q - Quit with a warm boot
The search command prompts (with a '?') for a string of up to 16
characters. If the string is not found 'No' is printed, otherwise the
next screen ending in the line containing the string is printed. The
continue command resumes the search, with the same string, on the
next line.
All letter commands and file names may be upper or lower case.
Ambiguous names are not allowed. The file extension may be anything
other than .COM, but it will look pretty weird if the file isn't a
text file.
