I am using VPLUS and Protos to write an application for the 9x7 and 9x8
series of machines (All on version 5.5 of MPE/iX or higher), that uses the
secure field enhancement.  The forms compile correctly, and my program does
as well.  When the program executes however and I issue the call to
VCHANGEFIELD to make the fields secure it returns the following error
message:

Error Number: +0852
Illegal Enhancement Type and error has occured on form <FORMNAME>

and the field is not secure.

My company has older applications that use secure fields using VPLUS and
Protos, and they still function correctly.  Has there been a change made to
either Protos, or VPLUS?  Is there a way to solve this problem?  I have
tried creating a duplicate of the forma and making the fields secure,
within formspec before compiling the forms file, but that has not worked
either.

Any assistance anyone can offer is greatly appreciated.  I am approaching
my deadline on this project and this is the last thing to be fixed.
