Also memory is properly conserved from 15 to 15.2 mode. No problem.

From 15.2 to 15 mode, it is conserved as long as no ram was used in the area abound the 15 mode. Example, if you have a 15.2 program using 800 steps and switch to 15 mode, it will not properly conserve memory. Same with data registers.

Safest usage in 15.2 mode would then be 51 DIM (i) so that MEM becomes 51142 00-0, with 142*7=994 programming steps
