EDIRECTION
Typically, tasks inherit their standard output from the loading context, such
as the entry station or standard output of a loader task. Sometimes, you must
redirect task output (print) to a different place, such as another entry station
or even a virtual entry station.
RedirectStdOut/RedirectStdOut$
provides this
capability.
-->RedirectStdOut task32.prg NewStdOut=1
-->
NewStdOut may be:
1 – Ethernet
2 – DPRAM
3 – Virtual Entry Station
4 – Etherent2
CAUTION
Systems with FPGA version 8.51, firmware 4.0.0 and higher
support IP over DPRAM.
NewStdOut
type is 1,3 or 4.

You can open a text file to read, write or append to the existing file according
to mode flag.
“r” - open text file for reading
“w” - truncate to zero length or create text file for writing
“a” - append; open or create text file for writing at end-of-file
