EMPTY SPACE
As you write longer programs, you will find that
the amount of memory space provided by the XL is
not unlimi ted. If a program uses large arrays for
data storage, the memory can be eaten up at an
alarming rate. The function FRE(X) tells you how
much memory is left unused.
Check the memory immediately after switching on
your XL, then enter a program and try it again -a
smaller number will be printed. If you RUN the
program and use FRE(X) a third time the number
printed will be smaller still, as the XL has taken
memory space to store the variables.
THE CLR COMMAND
The CLR command may occasionally be useful.
The command clears all the variables stored by a
program, but leaves the program itself intact. You
can then start a program with the maximum
amount of memory free.
