構造体、Fortran 95 派生型およびポインタを dbx で表示できます。

前述において dbx は、構造型のすべての要素を表示します。
構造体を使用して、Fortran 95 派生型の項目について照会できます。
Ask about the variable (dbx) whatis prod1 product prod1 Ask about the type (-t) (dbx) whatis -t product type product integer*4 id character*16 name character*8 model real cost real price end type product
dbx displays the contents of a pointer, which is an address. This address can be different with every run. (dbx) print prior prior = ( id = 82 name = ’Coffee Cup’ model = ’XL’ cost = 24.0 price = 104.0 )
