l.#
The INPUT # statement sequentially reads data items from the file opened for in-
put with the ROPEN # statement and assigns them to program variables. <variable>
may be an array element. <logical number > is the same number used as when the
file was first opened for input by the ROPEN # statement.
As with the READ ~ DATA statement pair, an error may be generated if data
and variable types disagree. The end of file can be tested by using the EOF # func-
tion if the specified file is on the RAM file board.
10 ROPEN #2, ““DATA2"
20 INPUT #2, A, B, C
30 PRINT A, B, C
40 CLOSE #2
50 END
This sample program reads numeric data from the file opened for input under logi-
cal number 2 and assigns the data to numeric variables A, B, and C.

Abbreviated Format
EO. #
The EOF( #) function is used to find the end of a file. This function signals an end-
of-file condition when all data in the file has been read. The value — 1 (true) is returned
after the end of the file is encountered. EOF(#) is invalid when reading data from
CMT.
The EOF(#) function is generally used with the IF statement and placed after an
INPUT # statement.
10 ROPEN #3, “DATA”
20 INPUT #3, A
30 IF EOF( #3) THEN END
40 PRINT A
50 GOTO 20
The above program reads data items sequentially from the file named ““DATA”’
and displays them on the screen until the end of the file is encountered.
