HLLAPI is the High Level Language Application Programming Interface that allows external programs to communicate with host computers using a TN3270, TN5250, VT, SCO ANSI or WYSE-60 terminal emulation program as the communication medium. The HLLAPI standard was defined initially by IBM. More recently, HLLAPI has been revised and updated by IBM, Microsoft, and a consortium of IBM terminal emulation vendors. The HLLAPI session short name and session long name allow HLLAPI applications to identify individual TN3270, TN5250, VT, SCO ANSI or WYSE-60 terminal emulation sessions. The HLLAPI session short name appears in parentheses in the upper left corner of the PASSPORT Window title for session identification. PASSPORT does not allow two sessions to have the same HLLAPI session short name.
Automatically Select
If selected, PASSPORT will automatically select the next available session short name and session long name. Session short names begin with A, then B, then C, and progress through the alphabet to letter Z. Session long names begin with SessionA, then SessionB, then SessionC, and progress through the alphabet to SessionZ.
Manually Specify
If selected, you must manually enter the session short name and session long name. This may be necessary if your HLLAPI application is hard-coded to a particular session short name and cannot be changed.
Short Name
You may enter a single alphabetic character (A to Z) to identify the session short name. HLLAPI applications use the HLLAPI short name to identify which session it is communicating with.
Long Name
You may enter a string of up to eight characters to identify the session long name. This name may be used by HLLAPI applications for session identification.
