After coding a SQL or dynamic SQL (DSQL) program, the program must be preprocessed with
gpre before it can be compiled.
gpre translates SQL and DSQL commands into statements the host-language compiler accepts by generating InterBase library function calls.
gpre translates SQL and DSQL database variables into ones the host-language compiler accepts and declares these variables in host-language format.
gpre also declares certain variables and data structures required by SQL, such as the SQLCODE variable and the extended SQL descriptor area (
XSQLDA) used by DSQL.
