Where did the cErrorsList go?

[Ben Rubinstein]

For years I've been accustomed to interpreting the error reported in a 'catch' 
statement using

put line xx of the cErrorsList of card 1 of stack "revErrorDisplay"


In 8.1.3, AFAICT, the stack "revErrorDisplay" has no such property.

The dictionary still recommends this technique.

Was there a flaw in the building process, or has there been a change (not yet 
reflected in the documentation)?

TIA,

Ben
