|Syntax||ABS_POSITION #channel, position|
This procedure will set the file pointer to the position given for the file attached to the given channel number. If you attempt to set the position for a screen or some other non-directory device channel, you will get a bad parameter error, as you will if position is negative.
If the position given is 0, the file will be positioned to the start, if the position is a large number which is greater than the current file size, the position will be set to the end of file and no error will occur.
After an ABS_POSITION command, all file accesses will take place at the new position.
