Open filename for binary access write as #1

Field definitions specify what data type each field is as well as other information that should be obvious by looking at the type. For sequential files, this value is the number of characters buffered. Your 3rd block code, or mine? Provide details and share your research!

You can omit this entry, in which case the next byte following the last Get or Put statement is read. The Binary file mode allows reading and writing of simple data type values, like Byte or LongIntusing binary read or write operations, like Get.

The syntax, as it applies to binary files is: Get [ ]filenumber, [byte position], varname The filenumber is any valid filenumber as defined above. The LOF function takes the filenumber of the file to be processed as its argument, and returns the length of the file in bytes.

Using your examples I have now rewritten the. Close 1 This code example opens the file in Binary mode for reading; other processes can't read the file.

The Input , Output and Append file modes also allow selection of a character encoding to be used when reading from or writing text to the disk file. The last things stored in the file are the actual records. When the application requests a record, the class converts the requested UDT Record to a Record object and passes it back to the application. However, when reading the file, we don't know so we have to continually redimension the array. The application doesn't care, nor does it need to know about the UDTs. In Append and Output modes, you must close a file before opening it with a different file number. Number less than or equal to 32, bytes. If we want our file to really be flexible then we probably won't be storing data that is always the same size and type. For example if you wanted to store three different kinds of UDT's, then you would have three RecordCount fields.

That happens to be the case here, so we could have done that. The last things stored in the file are the actual records.
