given (I) a 32 bit integer (with 0 being least significant and 31 being most significant) - is this the convention in FTN95?

Bitwise operations were included in the Fortran 90 standard and it is better to use these standard conforming intrinsics.

See the help file under FTN95 library -> Standard intrinsics (classified) -> Bitwise operations.

The old Salford bitwise intrinsics are mentioned in "Optimisation and efficient use of FTN95" -> "Intrinsic funcitons", but they are not documented in the help file.

I'm working on old FTN77 code where these functions are used, and am replacing them with F95 code.

I require the same the behaviour and so need exact descriptions of thes eold functions.

Here is an example of the code

Running the code under FTN77 and FTN95 respectively indicates that they are not the same.

Do you have access to FTN77? If not I assume that you can download a copy from the Silverfrost website.

The objective is to modernise some old code and run it under F95 or later (adopting the new standard)
I need to know the behaviour of the old functions so that I can replace them.

cheers

I assume that you do not have the FTN77 manual.
As far as I know they are now out of print but you could check with Silverfrost.

If you are a licenced user of FTN95 then I can send you a Word document for the relevant chapter. Please email me via this forum with your email address.
