Potential errors can come up when using allocatable arrays when returned in functions. Given the example found below, an error is created on purpose to demonstrate the compiled cannot detect it. Output: [mypc]$ gfortran allocarr.f90 && ./a.outvalues= -1 25 25 0 -1 -1 Bear in mind, potential errors could come from allocatable output arrays. Valgrind…

In order to read a REAL array, see the example below: Input param.nml: &param nrows=3, ncol=2, data_file=”hello.txt”, values=1.1, 2.2, 3.3, 4.4/ Output: mymachine:~/tests/namelist_arrays$…
