- keyldel - Delete key and value from keyed list
- keyldel listvar key
- This command deletes the key specified by key from the keyed list in listvar. This removes both the key and the value from the keyed list.
- Keyed lists are an extension of Tcl provided by the TclX package. They are an alternative to using ns_set, but we highly recommend using ns_set instead of keyed lists. The commands provided by AOLserver were taken directly from a 1995 version of the TclX package.
