The $BINARY
w. informat does not interpret actual binary
data, but it converts a string of characters that contains only 0s
or 1s as if it is actual binary information. Therefore, use only the
character digits 1 and 0 in the input, with no embedded blanks. $BINARY
w. ignores leading and trailing blanks.
To read representations
of binary codes for unprintable characters, enter an ASCII or EBCDIC
equivalent for a particular character as a string of 0s and 1s. The
$BINARY
w. informat converts
the string to its equivalent character value.
