Customizing for Fortran applications link-edited with VS FORTRAN

This section contains information about how to customize Language Environment if you have Fortran applications that were link-edited with VS FORTRAN Version 1 or 2 for running in load mode.

If you have such applications, you can customize, or not customize:

VS FORTRAN Unit Attribute Table defaults (See Changing the unit attribute table default values following.)
VS FORTRAN runtime option defaults (See Changing VS FORTRAN runtime option defaults.)
VS FORTRAN Error Option Table defaults (See Changing the error option table defaults.)

Note: Language Environment provides a VS FORTRAN compatibility library for running Fortran applications that are not link-edited with Language Environment.

You can customize Language Environment to provide certain runtime characteristics for Fortran applications that were link-edited with VS FORTRAN for running in load mode. You use macros with the same names as you used in VS FORTRAN Version 2 Release 6. These macros are VSF2UAT, VSF2UNIT, VSF2DCB, VSF2PARM, and VSF2UOPT. Each of these macros is available in Language Environment with these macro names as aliases for members with names beginning with AFH5. The use of these macros is identical to that in VS FORTRAN Version 2 Release 6; therefore, if you have assembler language source files that you used in the past, you can use these same source files to customize Language Environment.
