Allocatable Arrays:

Prism supports allocatable arrays in the same way that it supports pointers to arrays. Fortran 90 support includes the Prism commands print and whatis. Prism also supports slicing and striding Fortran 90 allocatable arrays. For example, to print a section of allocatable array alloc_array:

(prism) print alloc_array(1:30:2)

Fortran 90 language constraints apply. For example, Fortran 90 allows allocating or deallocating memory for an allocatable array but does not allow making an allocatable array point to another object. Therefore, Prism does not recognize pointer assignment, =>, to allocatable arrays.
