Thanks Bro.
Could you please illustrate this for me;
''After the FEND instruction, your pointer code is written with the pointer number on the outside of the ladder on the left''.
This is the only one I did not get clearly from the statement below of that Thread.
But in regular ladder to perform a subroutine you have to first call it with a pointer.
X0--------[CALL P1]....for example.
Then, at the end of the ladder, before the END instruction you would have a FEND instruction.
After the FEND instruction, your pointer code is written with the pointer number on the outside of the ladder on the left.
When the subroutine is finished you will need a SRET command to return to the other code.
