Chapter 9. Printer Control
You can specify what data is sent to the printer by using the )OUTSEL
system command or an APL shared variable. Also, at any time, you
can print all the information on the display screen by holding down the
CMD key and pressing the
m
key. When an APL shared variable
is used to send data to the printer, except for using the CMD
and
m
key, all the data to be printed must be assigned to
the shared variable. (See Input/Output Control for more information
on using shared variables for printing data.) The )OUTSEL command
has three options to specify which data on the display screen is
printed. These options are:
• ALL-specifies that all subsequent information displayed is printed.
• OUT-specifies that only output is printed. Even though input is
displayed it is not printed. For example:
~j·t
. .
3
L
If
you
enter this statement, the statement
is displayed but not printed.
~ _ _ _ _ _ ..;...The output (result) from the statement is displayed
and printed.
• OFF-specifies that none of the information displayed is printed,
unless an APL shared variable is used to send the data to the
printer.
You can use the following system variable and APL function to specify
the format of printed output:
• DPP Specifies the printing precision of numeric data (how many
digits are printed)
• 5 DCC n Specifies the starting print position (tab n) from the left
margin
•
~
Formats numeric data into character data
