I think this would be a useful addition to the hash commands. The -w switch could be added to /hinc and /hdec as well.

[htbl]
var.A 1
bob.B 2
var.C 3
var.D 4
bob.E 5
var.F 6
bob.G 7
var.H 8

/hinc -sw htbl var.* 3
- Incremented 5 matching hash items by 3


/hdec -sw htbl var.* 8
- Decremented 5 matching hash items by 8


/hadd -sw htbl var.* 43
- Set 5 matching hash items to 43



Can these be scripted? Yes. But then, so could have /hdel -w htbl var.* or /unset %var.*
