Intrinsics

The following IMAGE intrinsics are supported:

Intrinsic	Comments
DBBEGIN	Maps to BEGIN WORK
DBCLOSE
DBCONTROL	Only for special TRANSPORT™ modes
DBDELETE
DBEND	Maps to COMMIT WORK
DBERROR
DBEXPLAIN
DBFIND
DBGET	Mode 8 is deprecated to Mode 7. Item lists are supported.
DBINFO	Common modes supported
DBLOCK
DBMEMO	Only as a placebo
DBOPEN	Modes other than 1, 3, and 5 are mapped to 1. Passwords and file equates are not supported.
DBPUT
DBUNLOCK
DBUPDATE

DBGET mode 4 is supported, including the case when the application chain reads down Path #1, save the direct address and then does a DBFIND on Path #2, issues a DBGET Mode 4 with the saved direct address, and continues reading.

DBGET also allows additional modes that permit a WHERE and ORDER BY clause to be added to the SELECT statement.

DBGET employes extensive optimization to prevent repreparing of SQL statements.
