Laser 128 - Fre

BASIC FUNCTIONS
4.6 FRE
Purpose: Reports on the number of bytes
in memory that are not being
used by BASIC.
Format: FRE (expression)
Comments: Because strings in BASIC can
have different lengths , and need
to be manipulated . This
frequently causes the memory to
become very fragmented. Using
this statement with a dummy
argument can force BASIC to
Example:
gather up all the loose
fragments into contiguous
wholes (garbage collection) .
This frees up areas of memory,
and can often give you a
surprising amount more.
] X = FRE (0)
This would lead to a garbage
collection operation. It may take
some time.
] PRINT FRE (0)
In addition to a garbage
collection opera ti on, this would
print out the amount in bytes of
free user memory .
