dbx recognizes arrays and can print them.
demo% dbx a.out Reading symbolic information… (dbx) list 1,25 1 DIMENSION IARR(4,4) 2 DO 90 I = 1,4 3 DO 20 J = 1,4 4 IARR(I,J) = (I*10) + J 5 20 CONTINUE 6 90 CONTINUE 7 END (dbx) stop at 7 (1) stop at "Arraysdbx.f":7 (dbx) run Running: a.out stopped in MAIN at line 7 in file "Arraysdbx.f" 7 END (dbx) print IARR iarr = (1,1) 11 (2,1) 21 (3,1) 31 (4,1) 41 (1,2) 12 (2,2) 22 (3,2) 32 (4,2) 42 (1,3) 13 (2,3) 23 (3,3) 33 (4,3) 43 (1,4) 14 (2,4) 24 (3,4) 34 (4,4) 44 (dbx) print IARR(2,3) iarr(2, 3) = 23 - Order of user-specified subscripts ok (dbx) quit

The following example shows how to work with allocated arrays in dbx.
demo% f95 -g Alloc.f95 demo% dbx a.out (dbx) list 1,99 1 PROGRAM TestAllocate 2 INTEGER n, status 3 INTEGER, ALLOCATABLE :: buffer(:) 4 PRINT *, ’Size?’ 5 READ *, n 6 ALLOCATE( buffer(n), STAT=status ) 7 IF ( status /= 0 ) STOP ’cannot allocate buffer’ 8 buffer(n) = n 9 PRINT *, buffer(n) 10 DEALLOCATE( buffer, STAT=status) 11 END (dbx) stop at 6 (2) stop at "alloc.f95":6 (dbx) stop at 9 (3) stop at "alloc.f95":9 (dbx) run Running: a.out (process id 10749) Size? 1000 stopped in main at line 6 in file "alloc.f95" 6 ALLOCATE( buffer(n), STAT=status ) (dbx) whatis buffer integer*4 , allocatable::buffer(:) (dbx) next continuing stopped in main at line 7 in file "alloc.f95" 7 IF ( status /= 0 ) STOP ’cannot allocate buffer’ (dbx) whatis buffer integer*4 buffer(1:1000) (dbx) cont stopped in main at line 9 in file "alloc.f95" 9 PRINT *, buffer(n) (dbx) print n buffer(1000) holds 1000 n = 1000 (dbx) print buffer(n) buffer(n) = 1000
