PRINT #,

Syntax: PRINT expr

P. expr

? expr

PRINT#port,expr

P.#port,expr

?#port,expr

Where: expr = any string, mathematical number, or calculation

port = serial output port 0 or 1. Your card may have m ore ports.

Function: Prints value of expr to a serial port

Mode: Command, run

Use: PRINT "String",$(0),AIN(0)*.00214

Cards: PRINT#, P.#, and ?# only on RPC-320, RPC-330.

DESCRIPTION

PRINT is used to send serial data to any port. Default is COM 0. Use port or UO to re-direct output to COM

1 or others.

If there is no expr, a carria ge retu rn - line feed com binatio n is sent. expr is any combination of

instructions/operators and variables, strings, or literal values. More than one expr may be output by

separating them with commas. Values are printed with a leading and trailing space; a list of positive values

separated by commas will thus print with two intervening blanks. A "+" is implied. The "-" symbol precedes

negative values and takes the place of the normal preceding space. Strings and literals are output with no

added blanks. If a comma is the last character in the list then the normal <CR><LF> is suppressed.

The shorthand versions P. and ? are converted to PRINT after each program line is entered, so a P. or ? is

never listed.

The PRINT#port, instruction functions exactly like the PRINT instruction, but it directs output to the

designated serial port. When using this syntax, any output directed by the UO comm and is bypassed.

P.# and ?# are shorthand for PRINT#.
