VS2010

Dear Steve:

I just got my hands on VS Studio 2010 for real.

When do you expect Fortran support?

Do you know it is possible using IVF 11.1 to use code written in 1968 to analyze a Cretan jug that is 300 years old.

neat eh?

Hi John Our next major release scheduled for November will support VS2010. I do not know for certain whether IVF will understand the older code, butIVF supports Fortran 66. If need be, there is a /f66 option to enable specific Fortran 66 semantics, however, the option may not be needed. From the IVF documentation, this option causes the following to occur:

- DO loops are always executed at least once
- FORTRAN 66 EXTERNAL statement syntax and semantics are allowed
- If the OPEN statement STATUS specifier is omitted, the default changes to STATUS='NEW' instead of STATUS='UNKNOWN'
- If the OPEN statement BLANK specifier is omitted, the default changes to BLANK='ZERO' instead of BLANK='NULL'

Let us know if you run into any issues.

Just curious, what sort of analysis does the code do on the Cretan jug?

Dear Kevin:

The comment on the Cretan jug was a statement, not a question. The quality of a compiler I measure by how well it handles this old code and the error messages that are generated. The program was developed at USC by Powell's group of dynamic specialists, the program name is AXISHELL. It was written in 1968.

As I understand it I may have the only copy of the program in existence as the USC people can not find it and I can not find the original author. I have compiled the program on compilers from a main frame in 1981 when it was on cards, through Microsoft Fortran 3.31, at that stage a compiler would fit and run on two 360 k drives using a COMPAQ Portable. I turned then to Powerstation, but it was a dog of a program that gave me no end of trouble and cost an arm and a leg. I went onto Compaq Fortran, but I much prefer IVF, it is so much nicer with the error messages. it took about an hour to get the program running, mainly in relearning the aspects of the code.

The code does stress analysis, using a matrix inversion program. The beauty is the program takes a string line and turns it into 3d code. I can send you a sample if you like.

I made a mistake the pot is 3000 years old.

Old typists should retyre.

Ah, I see.Sorry for my misunderstanding.That's very cool to know IVF compiled it.
