In response to industry technology changes, support for EXTRA! 16-bit API options is limited. This technical note provides details regarding the support status for 16-bit APIs and available alternatives.
The EXTRA! Options Pack has included 16-bit API options as a transitional technology to enable legacy DOS and Windows 3.1x applications to make HLLAPI calls to EXTRA! X-treme. However, these APIs are deprecated and no longer supported by Attachmate.
The following EXTRA! 16-bit APIs are affected:
You may continue to use the 16-bit APIs at your own risk. Attachmate will no longer provide any patches or updates for 16-bit APIs. Attachmate no longer tests 16-bit APIs on newer Windows operating systems or with new Windows service packs and updates. Furthermore, 16-bit API options are not available in next-generation host connectivity terminal emulation products, such as Reflection for IBM 2007 or Reflection 2008.
You are encouraged to migrate your applications to use 32-bit APIs instead of 16-bit APIs. For information on 32-bit APIs in EXTRA! X-treme, see Technical Note 2164.
If you need assistance migrating your applications to use 32-bit APIs, Attachmate can provide consulting and development services. For more information, see http://www.attachmate.com/Products/Technical+Services/Consulting/.
For information on APIs available in other Attachmate products, see Technical Note 2183.
