Hi Lombardi,
Occasionally, I use malloc in FORTRAN programs.
But when I don't, I make a big static allocation in the main program,
and then do the I/O in subroutines, with variable length arrays.
For example
real mat(1000000)
...
nx = 5
ny = 6
nz = 7
call scribere(mat,nx,ny,nz)
The subroutine looks like this
subroutine scribere(myarray,n1,n2,n3)
real myarray(n1,n2,n3)
...
call ncvpt( CDFID, varid, START, count, myarray, ICODE )
You can make input subroutines that use this same feature.
Please write to me if you have more questions.
