detect_alt_ctrl

Syntax:

>>-----set detect_alt_ctrl=---.-TRUE-.-------------><
                              +-FALSE+

Parameters:

TRUE The run-time system detects the Ctrl, Alt, and Shift keys. These keys can then be used for COBOL utilities that would otherwise use the alternate key sequences of /c for Ctrl or /a for Alt. For example, the Development Environment is easier to use if detect_alt_ctrl can be set to TRUE.
FALSE The run-time system does not detect the Ctrl, Alt, and Shift keys.

Properties:

Default: FALSE
IDE equivalent: None

Comments:

Most UNIX environments do not detect input when the Ctrl, Alt, or Shift keys are available on a keyboard and are pressed by themselves. In these cases, detect_alt_ctrl must be set to FALSE. The operating system SCO Open Desktop from version 2 onwards does detect these keys individually and detect_alt_ctrl can be set to TRUE.
