This file contains vocabulary subsets of the main Expressions file (#757.01). Each sub-set is defined in file #757.2, and may
contain [pointers to] terms which are exclusive to a discipline (i.e., Nursing), a device (i.e., Grid Pad), or an application
(i.e., Order Checking, Encounter Form, etc).

757.21,.01 EXPRESSION 0;1 POINTER TO EXPRESSIONS FILE (#757.01) (Required)
EXP
LAST EDITED: MAR 02, 1994
DESCRIPTION: Contains a pointer to an expression (file #757.01), however, that expression (not the pointer) is
indexed in this file, thus creating the impression of a separate vocabulary.

^LEX(757.21,"B",EXP,IEN) - where EXP is the Expression (.01) pointer to the Expression file #757.01
and IEN is the Internal Entry Number of the Subsets file #757.21 where the expression pointer is
located.

^LEX(757.21,"C",EXP,IEN) - where EXP is a 63 character uppercase expression taken from the
Expression file #757.01 Display Text (.01) and IEN is the Internal Entry Number of the Subsets file
#757.21 where the expression pointer is located. This index simulates the functionality of the B
index in the Expression file #757.01.
757.21,1 SUBSET 0;2 POINTER TO SUBSET DEFINITIONS FILE (#757.2) (Required)
LAST EDITED: MAR 22, 1994
DESCRIPTION: Pointer to the subset definitions (file 757.2). This pointer indicates how the expression is to be
indexed (i.e., pointing to the Nursing subset in the definition file creates an index of the
expression with the cross-reference of "ANUR")

CROSS-REFERENCE: 757.21^AA^MUMPS
1)= D SS^LEXNDX2
2)= D SK^LEXNDX2
^LEX(757.21,IDX,WORD,IEN) - where IDX is the subset index (the letter "A" appended to the Short
Title of the subset taken from the Subset Definition file #757.2), WORD is a single word parsed
from the Display Text of the Expression file #757.01 pointed to by the expression (.01), and IEN is
the Internal Entry Number of the Subsets file #757.21 where the pointer of the expression
containing the WORD and the pointer to the Subset Definition are located. The "AA" index does not
exist physically. The indexing routine determines the vocabulary which is used (as pointed to in
the Subset Definition file #757.2, i.e., NUR). It then appends a leading "A" to the vocabulary
mnemonic (Short Title) creating a composite index identifier (i.e., "ANUR"). Finally, it parses
and indexes the words found in the expression (pointed to by the .01 field) using the composite
index identifier. For example, ^LEX(757.21,DA,0)= 262363^2, where 262363 points to the expression
"ABUSED ADULT, POTENTIAL" and 2 points to the Subset definition "Nursing" with the vocabulary
mnemonic "NUR", the words "ABUSED", "ADULT" and "POTENTIAL" would be indexed at
^LEX(757.21,"ANUR",WORD,IEN).
