Having recently obtained a Master 128, I have realised that it has extra characters allocated to CHR$ numbers 128 to 255. In order to define characters, it is necessary to use the VDU23 command; you cannot simply load the values into page &C as you can on the Electron. Here is a very simple way of converting the data to define the characters.
Add the PROCedure CHPROC (included in the Utilities directory on this disk) to the end of your program with the command:
OSCLI"LOAD U.CHPROC "+STR$(TOP-2) (RETURN)
Then add PROCch to a line after the data is *LOADed.
