Interface Procedures
Host Language Interface
058058 Tandem Computers Incorporated 6–3
Interface Procedures A host language program interfaces with ENFORM by calling the three procedures:
ENFORMSTART, ENFORMRECEIVE, and ENFORMFINISH. ENFORMSTART
initiates the query processor, ENFORMRECEIVE provides records to the host program
one at a time, and ENFORMFINISH terminates the query processor.
Each host application program interfacing with ENFORM must use: ENFORMSTART
once for each compiled query; ENFORMRECEIVE once for each record to be provided
to the host program (this is usually inside a loop); ENFORMFINISH once for each time
you complete processing with a particular query processor; and the necessary global
and local declarations.
A detailed description of each of the ENFORM procedures follows.
ENFORMSTART Procedure The ENFORMSTART procedure initiates the interface of a host program with
ENFORM. The syntax of the ENFORMSTART procedure is:
COBOL:
ENTER ENFORMSTART USING ctlblock
, compiled-physical-filename
, buffer-length
, error-number
, [ restart-flag ]
, [ param-list ]
, [ assign-list ]
, [ process-name ]
, [ cpu ]
, [ priority ]
, [ timeout ]
, [ reserved-for-expansion ]
FORTRAN:
CALL ENFORMSTART ( ctlblock
, compiled-physical-filename
,\ buffer-length \ , error-number
,[ \ restart-flag \]
,[ param-list ]
,[ assign-list ]
,[ process-name ]
