 |
|
Hello,
Im faced with this problem,
You cannot assign an expression of type OBJECT('System.UInt32') to a variable of type INTEGER(KIND=3)
Is there any way to handle a uint in FORTRAN code?
Thanks,
Alex. |

You can use transfer provided the uint fits in a 32 bit unsigned integer, if not you can use a combination of transfer and iand and a 64 bit integer.
| Code: |
program anon
object('System.UInt32') a
integer b, c
b = 12
! Just check size is 4 bytes
print *, 'Number of bytes in a = ', size(transfer(a,(/'A'/)))
! Assign b to a, i.e. a=b
a = transfer(b,a)
! Assign a to c, i.e. c = a
c = transfer(a, c)
print *, 'c = ', c
end
