Chapter 18: Memory and Variable Management 525
Archiving and unarchiving can be done in two ways:
•Use the
5:Archive or 6:UnArchive commands from the MEMORY menu or CATALOG.
• Use a Memory Management editor screen.
Before archiving or unarchiving variables, particularly those with a large byte size (such
as large programs) use the
MEMORY menu to:
• Find the size of the variable.
• See if there is enough free space.
Note: If there is not enough space, unarchive or delete variables as necessary. Be aware
that when you unarchive a variable, not all the memory associated with that variable in
user data archive will be released since the system keeps track of where the variable
has been and where it is now in RAM.
Even if there appears to be enough free space, you may see a Garbage Collection
message when you attempt to archive a variable. Depending on the usability of empty
blocks in the user data archive, you may need to unarchive existing variables to create
more free space.
System variables Xmin, Xmax, and others no not
applicable
For: Sizes must be such that:
Archive Archive free size > variable size
UnArchive RAM free size > variable size
