esqlf Command—Invoke Embedded SQL Preprocessor for Fortran
The esqlf command invokes the Ingres embedded SQL (ESQL) preprocessor for Fortran.
The esqlf command has the following format:
esqlf [flags] [filename]
flags
Specify options to the preprocessor.
These flags are common to most host language preprocessors, and are described under the esqlc command (see page esqlc Command—Invoke Embedded SQL Preprocessor for C).
The following flags are unique to the preprocessor for Fortran:
-iN
Sets the default size of integers to N bytes. N must be either 2 or 4. The default is 4.
On UNIX, if N=2 is used, the -i2 flag must be specified.
On VMS, if N=2 is used, the noi4 qualifier must be used.
-f90
Recognizes gfortran syntax for f90, and generates code using that syntax.
filename
Specifies the name of the file that contains the embedded SQL statements.
For a complete description of the SQL preprocessor requirements for Fortran, see the Embedded SQL Companion Guide.
