ACUCOBOL-GT treats each of the possible mouse actions in a manner similar to a function key. Each action has a unique key code that allows you to define the desired behavior by using the KEYSTROKE configuration variable. The following table details the mouse action, the corresponding key code, and the default exception value returned.
| Action | Key Code | Exception Value |
|---|---|---|
| Mouse moved | Mv | 80 |
| Left button pushed | Ml | 81 |
| Left button released | ML | 82 |
| Left button double-clicked | M1 | 83 |
| Middle button pushed | Mm | 84 |
| Middle button released | MM | 85 |
| Middle button double-clicked | M2 | 86 |
| Right button pushed | Mr | 87 |
| Right button released | MR | 88 |
| Right button double-clicked | M3 | 89 |
For example, if the user moves the mouse while your program is at an ACCEPT statement, that ACCEPT statement will terminate with an exception value of 80. Note that this will occur only if the mouse action is unmasked and your ACCEPT statement allows for exception keys. If the mouse action is masked or if the ACCEPT statement does not allow for exception keys, the mouse movement will be ignored.
