    But you may want to check out this post from Guido which uses a 74xx164 shift register and only uses 2 pins on the PIC with the HighJack routines.

    Thank you Darrel.
    Guido's way did not work in my simulator. I will make the real circuit assuming that the simulator could not simulate it.

    The circuit and the program work now. It's easily possible to drive up to three LCDs with only three I/O pins of the µC. Darryls "strings.pbp" work with only minor changes for my program. Thanks again, Darryl.
