| // DESCRIPTION
 | |
| //
 | |
| //  This example program takes the existing DOS00.GAL archive (create it
 | |
| //  with EX00CON if you don't have it) and deletes every other entry.
 | |
| //  Note that when we call Delete(), we specify an Archive with an empty
 | |
| //  name, which causes ALArchiveBase::Delete() to rename the input to a
 | |
| //  backup, and rename the output to the original input name.  Clear?
 | |
| //
 | |
| // REVISION HISTORY
 | |
| //
 | |
| //  February 1, 1996  2.0A  : Second release
