VERBON/VERBOFF
Field of Application Statements for specifying the verbosity level of the communication
from the printer on the standard OUT channel (serial communication
only).
Syntax VERBON|VERBOFF
VERBON enables all verbosity levels (default).
VERBOFF disables all verbosity levels.
Remarks
VERBON:
By default, when a character is received on the standard IN channel (see
SETSTDIO statement), the corresponding character will be echoed back
on the standard OUT channel. As the serial channel "uart1:" is by default
selected both standard IN and OUT channel, this implies that when you enter
a character on the keyboard of the host, the same character will appear on the
screen after having been transmitted to the printer and back.
When an instruction has been successfully executed, “Ok” will be displayed
on the screen, else an error message will be returned. Obviously, this requires
two-way communication, so verbosity has no meaning in case of the parallel
"centronics:" communication protocol.
VERBON corresponds to SYSVAR(18)=-1.
VERBOFF corresponds to SYSVAR(18)=0.
Other verbosity levels can be selected using SYSVAR(18), and the type of
error message can be selected using SYSVAR (19).
VERBOFF:
All responses will be suppressed, which means that no characters or
error messages will be echoed back. VERBOFF statements do not affect
question marks and prompts displayed as a result of an INPUT statement.
Instructions like DEVICES, FILES, FONTS, IMAGES, LIST, and PRINT
will also work normally.
Example This example shows how VERBOFF is used to suppress the printing of INPUT
data in lines 20 and 40 during the actual typing on the host, and VERBON to
allow the printing of the resulting string variables on the screen:
10 FOR Q%=1 TO 6
20 VERBOFF:INPUT "", A$
30 VERBON:PRINT A$;
40 VERBOFF:INPUT "", B$
50 VERBON
60 C$=SPACE$(25-LEN(A$))
70 PRINT C$+B$
80 NEXT Q%
90 END
