DOC - Open/Close a disk file that substitutes for the printer.
<pre>
Say you want to print to a file named "A:\inputs.txt" (it is not case sensitive).
 These are the 3 commands to enter on the RTES command line:
 
DOC A:\INPUTS.TXT 
PI
(here you should wait and make sure the task is over. Ideally, you would have a register
 named PRINT$ and it should go back to 0)
DOC
 
 
The DOC command is  toggle. The first time it opens the file (and needs a filename),
 the second time it closes it.
 
You could also do:
 
DOC database.txt
PI
PO
PA
PY
PR
PE
PT AUTOEXEC
PRINT RTES.CNF
(PRINT$ goes to 0)
DOC
 
Note that DOC opens a file for appending, so if the file already exists it just adds text to it.

The DOC command is also available as a task directive.

It is most often used with the PRINT command to produce reports.
