PRINT
Summary Information output
Syntax PRINT i or PRINT i;
Parameter i = information, for example, variables, text, CHR (n) separated by commas.
The CHR command returns the ASCII characters corresponding to a certain
number.
Description Calculation results, variables contents and text information can be displayed on the
connected PC via the RS485 communication interface by use of the PRINT com-
mand, if the APOSS software is open and the connection active.
To obtain multiple data with a single PRINT command, the individual elements
must be separated with a comma (,). Text information must be given in quotation
marks (").
A line feed is normally created following each PRINT instruction. This automatic line
feed can be suppressed with a semi-colon (;) after the last output element.
Command Group I/O
Cross Index INKEY
Syntax Example PRINT "Information is important !" /* print text information */
PRINT "Information is important !"; /* print information without line feed */
variable = 10
PRINT variable /* print contents of variables */
PRINT APOS /* print returned value function */
PRINT "Variable", variable,"Pos.:",APOS /* print mixed information */

PRINT DEV
Summary Stops information output
Syntax PRINT DEV nn printlist
Parameter nn = number for the device
0 = Standard output
-1 = no output after that line
printlist = normal argument for a print command
Description PRINT DEV can be used to disable all prints in a program without commenting them
out one by one.
The instruction (-1) defines the standard device new and is immediately effective
for all PRINT commands, that do not hold a DEV.
Command Group I/O
Cross Index PRINT, INKEY
Syntax Example PRINT DEV –1 "start"
