The PDX (V 1.5) application is granted read access to
the DD and DIC globals to accomplish the following tasks:
1) See DBIA 821
2) Get node a field/multiple is stored on
$P($P(^DD(FILE,FIELD,0),"^",4),";",1)
3) Get field name
$P(^DD(FILE,FIELD,0),"^",1)
4) Determine if a field is date valued
$P(^DD(FILE,FIELD,0),"^",2)["D"
5) Determine if a subfile is a word processing field
$P(^DD(SUBFILE,.01,0),"^",2)["W"
6) Determine what file a field points to
+$P($P(^DD(FILE,FIELD,0),"^",2),"P",2)
7) Determine if a file is a subfile
$G(^DD(FILE,0,"UP"))'=""
8) Determine main file number for a subfile
$G(^DD(SUBFILE,0,"UP"))
9) Determine main field number for a subfile
$O(^DD(MAINFILE,"SB",SUBFILE,""))
10) Determine subfile number
+$P(^DD(FILE,FIELD,0),"^",2)
11) Check for valid file number
$D(^DD(FILE))
12) Check for valid field number
$D(^DD(FILE,FIELD))
