# Practical Bank-Switching for the 2068

If any one factor can be said to have made the Pixel Print Prof. series of software possible, it would be the ability to hold the LEFT and RIGHT columns in memory at the same time, 48128 bytes of data plus the program! This was only possible with add-on memory and a programing tool called BANK SWITCHING!

Each of these routines could be used in some way with the PROF., the one I want to tell you about, however, will be used to MERGE the LEFT and RIGHT columns into 1 column!

The routine is 41 bytes long, it is relocatable, but must be used in the PRINTER BUFFER (23296) as no other memory is available…

To use this routine, prepare the two columns by erasing everything that you do not need… use the COPY function to move up or down the remaining data, switching between columns until ready,

Select SAVE, the ‘BREAK’, RANDOMIZE USR 23296: RUN (ENTER). Both L/R columns will be merged! POKE these values from address 23296 to 23336.
