Program EDDYBL

D .9 . ADAPTING TO OTHER COMPILERS/SYSTENIS 419D.9 Adapting to Other Compilers/ SystemsIf you change computers or compilers, the appropriate modifications mayalready be included in the source code provided . If your Fortran compileris an ANSI-77 Standard compiler and supports most of the standard VAXextensions, only three categories of changes are needed .1 . You must determine the correct syntax for the include command .Then, note that the source code provided uses the VAX syntax . Makethe appropriate change throughout the source code for your compiler .Examples of VAX and other syntax are :Fortran CompilerVAX, SVS, Lahey, MicrosoftCray (UNICOS), SUNMicrosoft (older versions)SVS (older versions)Cray (COS)Include Syntaxinclude 'filename'include 'filename'$include : 'filename'$include filename*CALL FILENAMEColumn 12 . Change the value of icpu defined in the include file named cpuid .The values currently assigned are :icpu = 0 SVS Fortran (680x0, 80386, 80486)icpu = 1 Lahey/Microsoft Fortran (8088, 80x86)icpu = 2 VAX/VMSicpu = 3 SUN Fortran (68020, SPARC)icpu = 4 Cray (UNICOS)icpu = 5Silicon Graphics Iris3 .4 .The only other compiler-specific syntax differences are located in asubroutine called NAMSYS that appears in eddybl.for . This subroutineopens disk files depending upon the value of icpu . Make anychanges required for your system .Search the EDDYBL and SETEBL source code for occurrences oficpu to see if the correct action is taken for your compiler and/oroperating system . Make any changes required for your system .5 . Modify Program INSTL as required for your video display and/orcompiler-specific requirements .
