| GENERAL DESCRIPTION |
This grants direct read access to the "V" nodes of a
field's DD. Descendent from the "V" node is information regarding variable
pointers including pointed-to file, message, order, prefix, screen, and LAYGO
status.
^DD(File#, Field#, "V", n, 0)
Where 'n' is a sequential number representing a different pointed-to file.
The pieces within this 0 node are:
^-Piece Contents
1 File number of the pointed-to file
2 Message defined for the pointed-to file
3 Order defined for the pointed-to file
4 Prefix defined for the pointed-to file
5 y/n indicating whether a screen is set up for the pointed-to
file
6 y/n indicating whether the user may add new entries to the
pointed-to file
^DD(File#, Field#, "V", n, 1) contains the M code defined as a screen on the
pointer to the file defined in the 0 node above. ^DD(File#, Field#, "V", n, 2)
contains a description of the screen.
Additionally, the following xrefs exist and may be read and traversed by
direct means, too:
^DD(File#, Field#, "V", "B" - xref on ^-Piece 1 of the 0 node.
"M" - 2
"O" - 3
"P" - 4
