COMPILER_VERSION

Module

USE ISO_FORTRAN_ENV

Syntax

result = COMPILER_VERSION( )

Results

The result is a scalar of type default character of processor-defined length.

The return value contains the name and version number of the compiler used for compilation.

Example

Consider the following file named t.f90:

use ISO_FORTRAN_ENV

character (len = :), allocatable :: res

res = compiler_options ()
print *, "len of res is: ", len (res)
print *, "('<<', A, '>>')") res

deallocate (res)
close (1)
end

The following is the output:
