EXPRESSIONS(#757.01)

  • 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.
    UNEDITABLE
  • CROSS-REFERENCE:  757.21^B
    1)= S ^LEX(757.21,"B",$E(X,1,30),DA)=""
    2)= K ^LEX(757.21,"B",$E(X,1,30),DA)
    ^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.
  • CROSS-REFERENCE:  757.21^C^MUMPS
    1)= S ^LEX(757.21,"C",$E($$UP^XLFSTR(^LEX(757.01,X,0)),1,63),DA)=""
    2)= K ^LEX(757.21,"C",$E($$UP^XLFSTR(^LEX(757.01,X,0)),1,63),DA)
    ^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.
1 SUBSET 0;2 POINTER TO SUBSET DEFINITIONS FILE (#757.2)
************************REQUIRED FIELD************************
SUBSET DEFINITIONS(#757.2)

  • 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")
    UNEDITABLE
  • 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).
