- I am wondering if it is possible to pass a Record Type and File Type to
- a Procedure in a Unit where the Record or File Type has not
- been declared. if it can be done I will need a little sample
- to get me going. Thanks in advance.
-
- Yes, as long as the Unit With the Procedure Uses the Unit in which the Types
- are declared. That's why it's frequently a good idea to move all your global
- Types and Variables to their own little Unit:
- }
-
- Unit Globals;
-
- Interface
-
- Type
- tMyRecord = Record
- Name,Address : String[40];
- Zip : String[5];
- { etc.}
- end;
-
- Implementation
-
- end. { of Unit Globals }
-
-
- Unit LowLevels;
-
- Interface
-
- Uses Globals;
-
- Procedure GetMyRecord(Var ThisRecord : tMyRecord);
-
- Implementation
-
- Procedure GetMyRecord(Var ThisRecord : tMyRecord); begin
- { whatever }
- end;
-
- end. { of Unit LowLevels }
-
-
- Program WhatEver;
-
- Uses Globals, LowLevels;
-
- Var
- MainRecord : tMyRecord;
- { depending on a lot of things, you might want to declare this
- Variable in the Unit Globals, rather than here }
-
- begin
- GetMyRecord(MainRecord);
- end.
