| DESCRIPTION |
This file defines each data segment currently supported by PDX.
Display methods must take the output of their associated extraction method
as input.
Global format of Display Array:
Root@("DISPLAY",line number,0)=information displayed on specified
line number of screen
Methods must use the following parameters (where needed):
ROOT - Where to store the information (full global reference)
DFN - Internal file number for requested patient (pointer to PATIENT
File)
SEGPTR - Internal file number of segment (pointer to VAQ - DATA
SEGMENT File)
XTRCT - Where the extracted information resides (full global
reference)
OFFSET - Where line numbering should begin from
TIMLIM - Time limit to apply to extraction
OCCLIM - Occurrence limit to apply to extraction
Methods must return the following:
0 - Extraction was successful (if an Extraction Array was returned)
n - Number of lines in display (if a Display Array was returned)
-1^ErrorText - Method was not successful
Sample methods:
$$EXTRACT^VAQZZZ(DFN,SEGPTR,TIMLIM,OCCLIM,ROOT,OFFSET) - Display
Array is
returned
$$EXTRACT^VAQZZZ(DFN,SEGPTR,TIMLIM,OCCLIM,ROOT) - Extraction Array
is returned
Global format of Extraction Array:
$$DISPLAY^VAQZZZ(XTRCT,SEGPTR,ROOT,OFFSET) - Display Array, built from
input extraction array,
is returned
Sample use:
S ROOT="^TMP(""VAQ"","_$J_")"
S SEGPTR=internal file number for segment
S DFN=internal file number of patient
S TIMLIM=time limit to use when extracting segment (if applicable)
S OCCLIM=occurrence limit to use when extracting segment (if
Root@("VALUE",file,field,sequence number)=value
applicable)
X ("S X="_^VAT(394.71,SEGPTR,"XRTN"))
The variable X is now set to the proper exit code (X<0 on error)
Root@("ID",file,field,sequence number)=identifier
Extraction methods must account for data encryption.
