[Simh] pdp7/decsys bug?

[Daniel Baum]

Hi all,

I have recently been putting various compilers and systems through their 
paces to see if I can get them to work.

I have had several successes (I will list them if anyone's interested), but 
I believe it is possible that there is a bug in the pdp7 simulator.

I have been playing with the decsys Fortran compiler. I have been able to 
compile and run programs, but it appears to have a problem with floating 
point variables.

The following:

            FLOATING POINT TEST
            AA=0.12345
            WRITE 2,200,AA
200      FORMAT(F8.5)
            END

gives .00000.

I am of course willing to assume that it might be me that's doing something 
wrong :~)

A similar routine with integers works as expected. Strings print out OK too.

Does anyone know where the problem is?

Thanks,

Daniel
