[#I
buffer,number
Transfers data from the communications line to the communica-
tions buffer.
Buffer
must be the same
buffer
assigned
to
the file when it was
opened. The number
sign
(#)
is
optional.
It
is provided for com-
patibility with other BASICs.
Number
is
the number of bytes to transfer.
Number
cannot ex-
ceed the value used in the LEN option of the OPEN COM
statement.
Note:
Because of the low performance associated with
telephone line communications, we recommend that
you
not
use GET and PUT statements in such appli-
cations. Instead, use the other disk 110 statements.
