I can't get PC-BASIC 15.03.5 to switch to Tandy video screen 5 or 6. After ensuring preset=tandy exists in pcbasic.ini and testing that I'm in Tandy mode with play "c","e","g" (and hearing a chord), screen 5 and screen 6 produce an ?illegal function call error.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Before using SCREEN 5 or SCREEN 6 in Tandy or PCjr mode, you need to execute the BASIC command CLEAR,,,32768! (note the three commas and trailing exclamation mark) to make (emulated) memory available to the video mode - this is also necessary on original Tandys.
I note that this is badly documented, I will adjust the documentation.
