Example
WRITE_TEXT(a,b,c,d)
(*text string a is written to a file
with the file name and directory
specified by variable b; if variable
d is 0, the text string is added to
the file along with delimiter speci-
fied by variable c; if variable d is 1,
a new file is created*)
Example
TXD_CPU(a)
(*text string a is sent from
the RS-232C port on the
CPU Unit*)
TXD_SCB(a,b)
(*text string a is sent from
the serial port specified by
variable b on the Serial
Communications Board*)
