  29 --  switches that are recognized. In addition, package Debug documents
  30 --  the otherwise undocumented debug switches that are also recognized.

  32 package Switch.B is

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