Declaration
Reset(FileVar, RecSize)
Parameters
| FileVar | [in] | Required | Variant | |
| RecSize | [in] | Optional | Integer | |
| Result | None |
Description
Opens an existing file associated with the file variable for reading. If the file is already open, it is closed and a new one is opened. The file pointer is set at the beginning of the file. If the specified file does not exist, an error occurs.
Parameters
The procedure has the following parameter:
FileVar
Specifies the file variable, which is associated with an external file by calling the AssignFile procedure.
RecSize
Specifies the record size (in bytes) to be used for data transfer.
| Note: | The RecSize parameter can be specified only for binary files. If this parameter is specified for a text file, an error occurs. If the parameter is omitted for a binary file, it is opened as a text file. |
Remarks
After executing the Reset procedure, the EOF function returns True if the file is empty. Else, it returns False.
