Additional edit descriptors are the colon (:),
the dollar sign ($), and Q; they perform
the following functions:
- The : edit descriptor terminates format control if no more
items are in the I/O list.
- The $ edit descriptor controls
carriage returns.
- The Q edit descriptor gets the
number of characters remaining following a partial read
operation.
See Table 8-1 for a summary of FORMAT codes.
