STRING statement plus 1. POKE$ does not check to see if it is writing over other variable information.

WARNING: RPBASIC-52 does not check the address. It is possible to poke into the program, stack, or

variable areas. Results are unpredictable. Poke into mem ory above MT OP for safest

operation.

Refer to the POKEB statement for segment and address information.
