Mode: COMMAND AND/OR RUN

This statement, along with CALL 77, allows you to save/retrieve

variables to/from a protected area of memory. This protected area is

not zeroed on power-up or when the RUN command is issued. The LD@

statement takes the variable stored at address [expr] and moves it to

the top of the argument stack. For more information on protecting

variables, see section 5.11.6, “Protected Variable Storage – CALL 77”.
