Syntax
BEGIN
Example
BEGIN DRIVER: FIND ALL RECORDS FOR WHICH RECTYPE = DRIVER END FIND NUM.DRIVERS: COUNT RECORDS IN DRIVER PRINT COUNT IN NUM.DRIVERS END
Usage notes
Every User Language request must be preceded by a BEGIN command or a MORE command and concluded by an END statement. After encountering a BEGIN command, Model 204 assumes that every input line entered by the user is a User Language statement (or a portion of a statement), until the user specifies an END statement.
Output from a User Language request appears on the user's terminal unless a USE command directs the output to an alternate device.
A BEGIN command is required even when a request is embedded in a stored procedure. User Language requests are described in detail in the Model 204 User Language Manual.
When BEGIN follows another command that does not automatically end its own update unit (for example, DEFINE), Model 204 ends any update unit in progress and begins a non-backoutable update unit. For more information about Model 204 update units, see the Model 204 File Manager's Guide.
