Notes
The bottom of the BASIC RAM depends on whether or not you have
DOS files loaded in. Without DOS, LOMEM should be 1792, with DOS
7420. If you increase or decrease the number of disk and sector buffers
by modifying DOS, this value will change again. See locations 743,
744 and 1801, 1802.
The size and location of the variable, string and array tables depend
on the program use and size. The more variables and arrays, the larger
the memory the tables use.
The size and address of the Display List and screen memory depend on
the GRAPHICS mode in use.
The first 256 bytes pointed to by LOMEM are the token output buffer.
The actual BASIC program starts at the address pointed to by VNTP.
