  36    --  Procedures to scan out front end switches stored in the given string.
  37    --  The first character is known to be a valid switch character, and there
  38    --  are no blanks or other switch terminator characters in the string, so
  39    --  the entire string should consist of valid switch characters, except that
  40    --  an optional terminating NUL character is allowed. A bad switch causes
  41    --  a fatal error exit and control does not return. The call also sets
  42    --  Usage_Requested to True if a ? switch is encountered.
