First, make your fortran file, e.g. integ.for.
For simple testing, make a main routine for testing e.g., testinteg.for . Compile, Link and execute your test program (examples are for VMS operating system):
$ FORTRAN testinteg $ FORTRAN integ $ LINK testinteg, integ $ RUN testinteg This program will return an array of running integrals array= 1.000000 2.000000 3.000000 4.000000 5.000000 16.00000 7.000000 8.000000 9.000000 running integral= 0.0000000E+00 1.500000 4.000000 7.500000 12.00000 22.50000 34.00000 41.50000 50.00000
