EHLLAPI
Emulator High-level Language Application Program Interface (EHLLAPI) is an enhanced version of HLLAPI.[1] It was introduced in 1986 by IBM in association with the IBM 3270 PC[2] to provide access from a DOS PC environment to data on an IBM mainframe.[3][4]
EHLLAPI can be used to determine screen characters, track and send keystrokes, check the host status and perform file transfers. Typically this API was employed for communication with existing mainframe applications without
the need to modify the application code.screen scraping.[7]
This IBM standard is supported by most terminal emulators.[8]
