RexxRMF.library version 1.8
Released March 1992
Release Info
Changes for version 1.8
Fixed bug that possibly would cause guru when deleting or
updating records.
RexxRMF.library does not like keys to be null, and will return an
error if a key is null, however record data fields can be null.
In version 1.8 if a record data field is null, RexxRMF will return
a string containing "(null)". I figure this would immediately catch
ones attention when displaying data fields. Even I got confused when
displaying data and saw nothing because it was null.
Function Enhancements
READ_RMF_RECORD
---------------
New read type 'L' added to allow reading in descending key order
(see docs for details)
DELETE_RMF_RECORD
---------------
New read type 'L' added to allow deleting in descending key order
(see docs for details)
ADD_KEY
-------
This function changed so that alternate keys can be linked.
(see docs for details)
FIND_POS
--------
This function changed so that the last node in the tree could be returned.
If 'pos' argument is negative then the last node in the tree is returned.
eg.
treenode = FIND_POS(ix,ixnum,-1)
will return the treenode of the last node (in sorted order) in the tree
(see docs for details)
