please check your lookup
filename or C disk size.
Several key arguments as below:
FilePath$ DBMS file path
DBMSID% DBMS ID (1~10)
S1$ This argument has two kinds of meanings.
 When search for regular length, it needs to
insert the unsigned char array; the array
represents the length of every field.
 When search for variable length, it needs
to insert one character to represent separate
symbol.
S2$ This argument can give max. 8 key fields for
search. We will make a checksum index file for
these key fields.
N1% This argument can give the sum of key fields
size.
N2%
 When N1%=0, search for regular length. It
has no separate symbols between different
fields.
 When N1%=1, search for variable length.
It needs a separate symbol between
different fields.
N3%
This argument is each record‟s length.
 When N1%=0, needs to insert this value,
not including the symbol of line feed.
 When N1%=1, this field can insert any
value.
N4%
This argument is the field‟s quantity of each
record (1~20).
