I have several questions about I/O that may or may not be related but any help would be appreciated.
I made a fortran dll that I want to use in VB How do I send the location and name of the at file to the dll? Can I send it the path name as a variable (assuming the at file is in a different location that the dll)?
Can I assign UNIT numbers to different locations (yes, I know there are default unit numbers)? Where do I do that?
Suppose I made a different dll that reads and writes to an Access data base, how do I do that? Specifically, do I use OPEN statements? What would the UNIT number be? If I want certain read statements to be assocaited with certain locations in the database (ie: rec=14), how will I know what the record numbers are associated to which record? Now, when they say record number, is that refering to a cell? a sheet? a database? And, if the data base is in a different location than the dll, how do I tell the dll where to find the database?
And lastly, if you could point me in the direction of some good (helpful) books regarding these more complex questions, I would greatly appreciate it.
