Specifies whether the UNIX environments detects input when the Ctrl, Alt, or Shift keys are available on a keyboard and are pressed by themselves.
Note:
Restriction:
These tunables are supported for native COBOL only.
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

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.
