The Default Compiler
When you name a file with a standard file extension (.MAC, .CBL, .FOR,
.ALG), the compiler implied by the extension will be used to compile
the program. Standard file extensions are listed in the help file
FILEXT. You cannot override the compiler that is implied by the file
extension. The COBOL compiler will compile a file called DATPRO.CBL.
Files without a recognizable compiler extension are compiled by the
default compiler, normally FORTRAN.
If you have a file with a non-standard file extension, you can control
the setting of the default compiler (FORTRAN) by including switches in
the COMPILE, LOAD, EXECUTE, or DEBUG command string. The help files
for the COMPILE, LOAD, EXECUTE, and DEBUG commands include the
switches you can use to change the default compiler.
In the following examples, the installation has chosen FORTRAN as the
default compiler. If you issue the following command:
the file named NOEXT will be compiled by FORTRAN. The following
causes the file named FILEZ.MIN to be compiled by FORTRAN because MIN
is not a recognizable compiler extension. The following command:
causes the files APART and TEST to be compiled by FORTRAN and the file
DATA to be compiled by COBOL.
By setting the appropriate assembly switches you can
indicate SNOBOL, BLISS, or MACY11 as the compiler.
However, these switches and compilers are not
The switches that change the default compiler can be temporary or
permanent. For more help on switches, see the help file SWITCH.
