VERBON/VERBOFF
Chapter —Program Instructions
Purpose 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
