Ladybridge Releases 3.4-6 of QM

This release is mainly to correct an issue described in section 5 but also includes the following enhancements.

The DECRYPT.FILE command can be used to cancel encryption for a file or specific fields.

The OSCOPY command and corresponding !OSCOPY() subroutine have been extended to allow appending to an existing file.

The QMBasic ELEMENT.EXISTS() function can be used to determine whether a named element is present in a data collection.

The compiler no longer reports an error if a subroutine argument passed as a matrix is not dimensioned.

The QMSAVE tool (see http://www.openqm.com/cgi/lbscgi.exe?T0=h&t1=kb.00011) has been modified to add verification of the file and record counts.
