Metamorph Index Default Type Is INVERTED - Caveat

In Texis version 7 and later, the default Metamorph index type is INVERTED, as it is more useful than non-inverted and the most commonly used variant.

Caveat: Thus, in version 7 CREATE METAMORPH INDEX ... (with no other options) will create an inverted Metamorph index, not a non-inverted Metamorph as in previous versions.

To create a non-inverted index in version 7 and later, use the WORDPOSITIONS 'off' index option. Search the online Texis manual for "Index Options" for more details. This behavior change is rolled back if <vxcp compatibilityversion> is set to 6.
