%eval should NOT parse alias names!
>#ALIAS foo {bar}
>#SHOW %eval(foo)
no output
>#UNALIAS foo
>#SHOW %eval(foo)

Either way, an alias with numbers starting it will not get fixed.

From the help page for %eval:
| Quote: |
NB: Do not use this function unless you're sure you have to. While it was used very often in zMUD, most of its uses have been deprecated in CMUD. In CMUD, evaluating an expression is as simple as surrounding it in brackets.
Use of this function is inadvisable because its argument is treated as a string and only compiled at runtime, which is slower than simply using brackets.
|
In other words, just use (135-16) instead of %eval(135-16) |

zMUD was never intended to allow numeric alias names either. It was actually a bug in zMUD. For compatibility, CMUD has some limited support for aliases that start with or contain numbers, but they will only work from the command line and not from within scripts.
And yes, as Rahab said, you should be getting rid of most of your %eval calls in CMUD. They are no longer needed. |
