When VA FileMan routines are invoked with the local variable DUZ(0) set to the at-sign (@), the user is understood by VA FileMan to be an M-proficient developer who has "Programmer access." Those working with Programmer access can control certain file-definition options that are otherwise handled invisibly by VA FileMan. These features are described in this section.
CAUTION: Programmer access in VistA is defined as DUZ(0)="@". It grants the privilege to become a developer in VistA. Programmer access allows you to work outside many of the security controls enforced by VA FileMan, enables access to all VA FileMan files, access to modify data dictionaries, etc. It is important to proceed with caution when having access to the system in this way.
REF: For a description of the file and field definition options available to everyone, see the "Creating Files and Fields" section in the VA FileMan Advanced User Manual.
