fileobject.SEEKBEGIN(<position>)

Required Argument

position

an integer specifying the number of bytes that need to be moved forward from the beginning of the file. Specifying a 0 means the start of the file. This parameter can be specified as a number, field name, or expression.

Details

The SEEKBEGIN method moves the file pointer to the specified location in the file, where 0 indicates the start of the file. It returns true on success. Otherwise, false is returned. Specifying 0 means that reading starts after the first position in the file.

Example

file f
string input
 
f.open("C:\filename.txt", "r")
 
input = f.readline()
 
// return the pointer to the beginning of the file
// and read the first line again
f.seekbegin(0)
f.readline()
 
f.close()
