The WOPEN # statement opens a BSD file for output. It also assigns a logical number
and name to the file.
<device name> may be omitted when the default device or the device specified
in the DEFAULT statement is to be used. Specifying RSn as < device name> causes
output to be sent to the RS-232C device.
10 WOPEN #1, ‘‘CMT:DATA”’.... Opens a file under the name ‘‘DATA”’ for out-
put and assigns logical number | to that file.
.. After this statement is executed, all output from
PRINT #1 statements is sent to the RS-232C
port.
10 WOPEN #1, ‘‘RS1:"'
10 WOPEN #2, ‘‘DATA’’
