If you add a watch for a set variable you by default get the value in dotted display like this:
| MyVar | [firstvalue ... lastvalue] |
Unfortunately this only helps if you know all the values that are between the two given ones. And usually, you don't. (OK, usually I don't, you of course do. ;-) )
There is, however, the undocumented display format modifier "e", that changes this display to much the more convenient:
| MyVar,e | [firstvalue, secondvalue, thirdvalue, lastvalue] |
Now, if only that was the default....
