n: iexp

expression: aexp or sexp or a combination

PRINT #n outputs data to a specified channel. Parameter n (0 to 99) denotes the
required channel. Otherwise the instruction operates like PRINT. PRINT #n AT,
however, is not possible.

PRINT #n USING allows formatted output to a data channel. The parameter n (0 to
99) denotes the required channel. Otherwise the instruction operates like PRINT
USING.

The instruction WRITE # serves primarily for the space-saving storage of data
in sequential files in a format suitable for later reading with INPUT #. The
expressions are separated by commas and character strings must be enclosed in
quotation marks. The parmater n (0 to 99) denotes the required channel.
Otherwise the instruction operates like WRITE.

Examples:

    OPEN "o",#1,"TEXT.DOC"
    PRINT #1,"test"
    CLOSE #1
    '
    OPEN "i",#1,"TEXT.DOC"
    INPUT #1,a$
    CLOSE #1
    PRINT a$

--> The string 'test' is printed to the file TEXT.DOC, which is then closed and
    re-opened for input. INPUT # takes the string from the file as a$, which is
    then printed on the screen.

    OPEN "o",#1,"TEST.DAT"
    WRITE #1,"Version ",3,".0"
    CLOSE #1
    '
    OPEN "i", #1,"TEST.DAT"
    INPUT #1,v1$,v2$,v3$
    CLOSE #1
    PRINT v1$+v2$+v3$

--> Data separated by commas is put into the file TEST.DAT and afterwards read
    back in again with INPUT # and displayed on the screen.
