(c) if B then F1 else '(E20.6)' .
(3) list is as defined previously. Of course, for INPUT all expressions must be variables.
The following are examples of an INPUT statement:
INPUT (50, '(4E20.8)', N, for I := 1 step 1 until N do A[I]).
INPUT (if A < B then M else N, F, X, Y, Z) .
Each INPUT statement causes at least one card image to be read.
Note that the INPUT procedure does not make type checks between the data and the program variables. A floating point number, for example, is stored as such regardless of the type of the variable to which it is assigned.
Caution. It is strongly recommended that not both READ and INPUT be used in the same program. Each buffers ahead one card image. Furthermore, each INPUT statement causes at least one card image to be read while a READ statement may not cause a new card image to be read. Mixing the two statements will require quite careful use of blank cards in the data to allow for the buffering.
OUTPUT
The OUTPUT procedure is used to output numbers and Hollerith information in accordance with Fortran-type formats. An OUTPUT statement has one of the forms
