26 -- This package scans binder switches. Note that the body of Usage must be
27 -- coordinated with the switches that are recognized by this package.
28 -- The Usage package also acts as the official documentation for the
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
33
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.
