Preprocessor Modes
You can use the preprocessor in two modes:
1. Syntax checking mode, which only checks your SQL syntax.
2. Full preprocessing mode, which includes SQL syntax checking,
creating compilable output, storing a module in a DBEnvironment,
and creating a file that contains an installable copy of the
stored module.
As you develop the SQL portions of your FORTRAN programs, syntax checking
mode is quite useful. Preprocessing is quicker in this mode than in full
preprocessing mode. In addition, you can start debugging your SQL
commands before the DBEnvironment itself is in place.
How to run the preprocessor in both modes is described later in this
chapter under "Invoking the FORTRAN Preprocessor."
