DCL allows the user to type any nonambiguous abbreviation
of a keyword. Unfortunately, CLI$GET_VALUE only returns
exactly what was typed, not the full keyword.
To get around this, I have had to maintain a list of known
keywords in a program, call CLI$GET_VALUE, and then look
for a match in the list of keywords that I keep in sync
with the CLD.
How can I get the acutal keyword? If that's impossible,
how can I find the table of possible keywords for a CLI
entity, and what does it look like?
