8.6 BASIC Monitor Commands
P Command (Print switch)
Format
Explanation
e
This command outputs the data produced by the D or F command to the printer
or screen depending on whether the current operating mode is the printer mode or
the screen mode. When the BASIC monitor is started, the screen mode becomes
valid. The mode is changed each time the P command is entered.
In the printer mode, if no printer is connected or the printer is off-line, the monitor
prompt (*) is displayed preceded by the message ‘‘ERR?’’.
Check the printer or key in the P command to enter the screen mode.
