The DEFINE-ENVIRONMENT statement defines the SDF-A version to be used and thus the syntax file format in which the processed syntax file is stored. This statement must be explicitly executed before creating or opening a syntax file whenever the user does not wish to work with the highest SDF-A version. Note that syntax files cannot be processed with a lower version than the one with which they were created or stored.

SYNTAX-FILE-FORMAT =
Defines the SDF-A version to be used.
SYNTAX-FILE-FORMAT = *CURRENT / *V4.1
SDF-A V4.1 remains loaded, so subsequently processed syntax files are stored in V4.1 format.
SYNTAX-FILE-FORMAT = *V4
SDF-A V4.0 is loaded, and the complete functionality of SDF-A V4.0 is available to the user. Subsequently processed syntax files are stored in V4 format.
SYNTAX-FILE-FORMAT = *V3
SDF-A V3.0 is loaded, and the complete functionality of SDF-A V3.0 is available to the user. Subsequently processed syntax files are stored in V3 format.
