// 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
