It is sometimes convenient to use an Indirect Command File to direct the
flow of an Application Program, whilst still prompting the Operator to supply
information at run-time. This feature is allowed by use of the ``#" character.
If this is detected within an Indirect Command File then it causes one line
of Input to be taken from the direct input device (normally the keyboard),
before returning to the Indirect Command Procedure for further input. If this
character is the first character within a word, the remainder of the word will
be ignored. If this character is detected in direct input mode it is treated
as a null response (all spaces) but will be inserted into any LEARN File if
appropriate.
