Although Windows runs on top of MS-DOS, it uses the keyboard differently. If you compared ACUCOBOL-GT for Windows to ACUCOBOL-GT for DOS, you'd notice the following differences.
Additional keys
In addition to the keys listed in User's Guide Chapter 4, these extra keys are available for the Windows system only:
| Ctl-Ins | for Insert Line (kA) |
| Ctl-Del | for Delete Line (kL) |
User-defined keys
User-defined keys 1 - 6 (U1 - U6) are:
| F11 | U1 |
| F12 | U2 |
| Shft-F11 | U3 |
| Shft-F12 | U4 |
| Ctl-F11 | U5 |
| Ctl-F12 | U6 |
User-defined keys 11 - 20 (A1 - A0) are:
| Ctl-1 | A1 |
| Ctl-2 | A2 |
| Ctl-3 | A3 |
| Ctl-4 | A4 |
| Ctl-5 | A5 |
| Ctl-6 | A6 |
| Ctl-7 | A7 |
| Ctl-8 | A8 |
| Ctl-9 | A9 |
| Ctl-0 | A0 |
Note that Alt key sequences and F10 are directly handled by Windows and cannot be referenced in COBOL. However, you can free the F10 key to act as a user defined key by using a configuration variable. Setting the F10-IS-MENU variable to "0" will inhibit the standard menu activation capability for the F10 key. See Book 4, Appedix H for more details.
