| -- This package scans front end switches. Note that the body of Usage must be |
| -- coordinated with the switches that are recognized by this package. |
| -- The Usage package also acts as the official documentation for the |
| -- switches that are recognized. In addition, package Debug documents |
| -- the otherwise undocumented debug switches that are also recognized. |
| |
| package Switch.C is |
| |
| procedure Scan_Front_End_Switches (Switch_Chars : String); |
| -- Procedures to scan out front end switches stored in the given string. |
| -- The first character is known to be a valid switch character, and there |
| -- are no blanks or other switch terminator characters in the string, so |
| -- the entire string should consist of valid switch characters, except that |
| -- an optional terminating NUL character is allowed. A bad switch causes |
| -- a fatal error exit and control does not return. The call also sets |
| -- Usage_Requested to True if a ? switch is encountered. |
