----------  Pager and Printer ----------

In any Empress command where the clause "into FILE" may be used, the
keywords "pager" or "printer" may be used instead.

"Pager" sends the output of the Query Language command  to  a  paging  program
which  displays  one screenful of output lines at a time, and prompts the user
for the next screenful.  The operating system utility program used for  paging
is  defined  by  the Empress system variable MSPAGER. 

The default for MSPAGER under UNIX is "more".

"Printer" directs the output of the Query Language command to  a  printer  via
the operating system utility program defined by the Empress system variable
MSPRINTER. The default for MSPRINTER under UNIX is "pr | lpr".  If there is no
printer on the system, the command will execute but nothing will happen.

With one exception, wherever the clauses "into FILE" and "from  FILE"  may  be
used,  FILE may be replaced by "!OS_COMMAND".  (i.e. using "into pager" is the
same as specifying "into !more").  The exception is  the  SET  command,  which
must take a file name if "from FILE" is used.
