I have a IVF10 DLL that is the calculation engine for a frontend application written in VB.NET 2005.
I've noticed that when I pass a Boolean/Logical from VB.NET to IVF10 as part of an argument list, when I try to evaluate it it only evaluates correctly if I type it without the "dots" before and after the TRUE.
IF ( BVAR.EQ.TRUE ) THEN
BVAR is declared this way:
LOGICAL*2, INTENT(IN) :: BVAR
And on the VB.NET side BVAR is declared this way:
Dim bVar as Boolean
However, if I declare a variable that exists solely withing the IVF10 DLL and assign it's value from with the DLL, rather that having its value passed from VB.NET, then the "dots" are necessary or it won't evaluate correctly.
IF ( CVAR.EQ..TRUE. ) THEN
CVAR is declared this way:
Can anyone please shed some light on this behavior? Thanks in advance.
