[value] attribute from powerstation 1 problem

Intel_C_Intel — Tue, 15 May 2001 23:04:24 GMT

I am porting thousands lines of Fortran Powerstation 1 source code to Visual Fortran 6.5.
I am having problems with proc/func interface declaration : In the following code :

interface to integer function pal_def(i[value])
integer i
end

The [value] attribute doesn't go with VF 6.5 complier.
One solution would be to change it to :

interface to integer function pal_def(i)
!DEC$ ATTRIBUTES VALUE :: i
integer i
end

Too long. I have thousand of line to change !

Is there a simple solution ? (compiler option, utility...)
Is there some other powerstation-specific problem I should pay attention to ?

Yes, Visual Fortran does support [VALUE]. However, it does not support "file scope" placement of INTERFACE TO blocks at the beginning of the source file. You would have to move the INTERFACE TO blocks inside the routines that use the interfaces, or put them in a MODULE which you then USE in the routines.

reply to Steve L. Thank you for your answer... but :
Moving the INTERFACE TO blocks inside the routines and putting the blocks in a MODULE don't help.
It seems that VF6.5 doesn't accept [VALUE] statement in the function/procedure head line.
For example :
integer function FSUB (I[VALUE],J[VALUE])
FSUB = I * J
return
end

doesn't work. Compiler says :
Error: Syntax error, found '[' when expecting one of: , : )

I'd have to see a small but complete example. Please send it to vf-support@compaq.com
