is the number of the record. Must be ≠ 0.
Remarks The GET statement is used to read a certain record in a certain random file
to a buffer, where the record will be assigned to variables according to the
FIELD statement given for the buffer. After the GET statement has been
executed, you can use references to the variables defined by the FIELD
statement, to read the characters in the random buffer.
Numeric expressions, which have been converted to string expressions by
STR$ functions before being put into the buffer, can be converted back to
numeric expressions using VAL functions.
