The Compiler and the Linker

Figure 1-3 “Compile-Time and Link-Time Events” summarizes the steps in creating an executable ALLBASE/SQL FORTRAN program from the files created by the FORTRAN preprocessor.

You must use native mode to compile and link your program.

You submit to the FORTRAN compiler a modified source code file and the related include file(s) created by the preprocessor. The compiler then generates an object code file. To convert one or more object code files into an executable program, you link them by invoking the linker. This step creates an executable program file. Refer to the Chapter "Using the ALLBASE/SQL FORTRAN Preprocessor" for more information on compiling and linking.

The following example illustrates the preprocessor storing a module in a DBEnvironment located in a group other than that in which preprocessing was initiated. An executable program named SOMEPROG is created in the GROUP1 group after a module named SOMEMOD is stored by the FORTRAN preprocessor in a DBEnvironment named SOMEDBE.GROUP2.ACCTDB. Note that PGMR1 must have appropriate ALLBASE/SQL and operating system file authorities as well.

        :RUN PSQLFOR.PUB.SYS; INFO = 'SOMEDBE.GROUP2 (MODULE(SOMEMOD))'
