VPRINT
Command
--------------------------------------------------
Purpose: Creates a "virtual printer" by redirecting
all printer output to a disk file.
Format: VPRINT [filespec] [/N]
Type: Internal External
***
Remarks: Printer output is redirected to the
specified file, or if none is given, to
VIRTUAL.PRN. To avoid overwriting
existing data, no redirection occurs if
the file is already in the directory.
Output is buffered up until a sector's
worth of data is available.
The command VPRINT /N cancels redirection
and flushes the buffer to disk.
The primary intended use of VPRINT is
the simplified creation of formatted DOS
files from Easywriter. By printing to
disk, it is not necessary to manually add
end of paragraph markers at the end of
each line, or to use the Easywriter
utility TRANSFER.
Note: VPRINT is still in an experimental form.
Use of the PrtSc key while redirection
is in effect will cause a system crash.
On the author's 64K system, a single 5
digit number overwrites five charactors
near the beginning of any file loaded by
Easywriter. This overwrite can be
corrected with the editor prior to
printing.
