AllowTypeAhead

Valid for: SetStartup

Syntax -

       SetStartup AllowTypeAhead {"Yes" | "No"}

Description:

This option determines the setting for the Rumba Edit Option, Type Ahead.  A setting of "No" for this option will cause EMUE to verify that the mainframe connection is ready to receive before sending any information.  AllowTypeAhead sets the Allow Type Ahead checkbox on the Misc. tab of the EMUE Tools - Current Settings - Option Settings window.  Enabling this option can dramatically improve performance, by allowing keystrokes queued ahead by Rumba even if the mainframe has not acknowledged that is ready to receive.  However, it is suggested that this is tested carefully before implementing this in production, as some systems may show synchronization issues.

Note: Some Microsoft SNA systems using the Microsoft SNA client (not TN3270) show contention when this option is set to “No”.  Setting this option to "Yes" has been shown to alleviate this contention.

Note: If script execution on a Microsoft SNA client PC is interrupted by returns to a blank screen or a login screen, enabling this option should remove the problem.

Sample:

       The following statement sets AllowTypeAhead to Yes so that the Rumba edit option type ahead is enabled.

SetStartup AllowTypeAhead "Yes"
