VA FileMan DIC

The VA FileMan ^DIC API, is used to find an entry in a FileMan file.

there are several main entry points:

Classic FileMan

These routines use local variables in the symbol table as the parameter passing style.

Lookup/Add

Given a lookup value, these entry points search the requested Index(es) on a file and either

1. find a matching entry,
2. add an entry to the file, or
3. return a condition indicating that the lookup was unsuccessful.

There are three APIs to lookup an entry in a file, they only differ in the way they use cross-references to do lookup. The three entry points perform lookups as follows:

• <mrou>DIC</mrou> : Starts with the B cross-reference, or uses only the B cross-reference [unless K is passed in DIC(0)].
• <mentry>IX^DIC</mentry> : Starts with the cross-reference you specify, or uses only the cross-reference you specify.
• <mentry>MIX^DIC1</mentry> : Uses the set of cross-references you specify.
