Addition of New EHLLAPI Parameter to Hide Non-Display-Type Fields

       Disclosed is an expansion to the Emulation High Level
Language Application Programming Interface (EHLLAPI) product
available under OS/2* 1.3 that allows applications to prevent the
return of data from non-display-type fields.

      The Emulator High Level Language Programming Interface is an
IBM product that enables interaction between 3270 and 5250-type
emulation sessions running under the OS/2 Extended Edition 1.3
Communications Manager. An EHLLAPI application program acts as a
programmed operator (a program that performs and monitors activities
in a workstation that are usually done by a human). Examples of this
are:
      1. Automation of repetitive tasks
      2. Consolidation of several complicated tasks into a
         single simple task.
      3. Simplification of existing host application
         interfaces.
      4. The monitoring of response time and availability.
      5. Automation of console operations.
      6. Transfer of data between the host and PC.

      In prior releases of EHLLAPI the functions that copied text
from the emulation session screen would return all data, regardless
of the type. This created potential security problems when screens
containing data in non-display fields (i.e., passwords) were returned
unmodified to the requestor. This invention adds two new parameters
to the EHLLAPI Set Session Parameters (9)...
