As data is read from or
written to a file there is a pointer inside the file which keeps
track of how far through the file it has got. This command simply
sets the position of this pointer.
fileId is the id of the file obtained
from Ask Open File or Open
File. If the file is not open or invalid then this will cause
an error.
pos is the new position of the file.
This is different depending on the data format of the file.
Data File
The position indicates the amount of data that has been stored.
Integers and floats are both 4 pieces of data long. A string
is the length of the stored string plus 1.
Text File
The position indicates which line of the text file to access.
Each piece of data should be stored on a separate line.
