Hi Tony
If you are using Powercobol, you can link a dll file into the project, loading and declaring a .lib resource for the dll you want to use.
If you haven't the .lib to call the dll, you can refer to it putting on the COBOL85.CBR file an ENTRY with the name you will use in your applications then the complete pathname of the dll file.
Ex.
[ENTRY]
myDll=C:\mypc\mylibrary.DLL
Hope in this help.
