/unset
Indice
The /unset command removes any variables by their specified names. If a wildcard pattern was specified, all variables matching that pattern will be removed. The /unset command can be used to remove both local and global variables, however it can only remove one of them per name. Local variables take precedence over a global variable with the same name.
Note: /unset has an evaluation issue with dynamic variables, you can read more here

Synopsis
/unset [-s] <%var> [%var2 [%var3...]]Switches
- -s - Display an output showing the variables that are unset
Parameters
None
Example
The most basic usage is to unset a specific variable:
/unset %foobarLocal variables take precedence over a global variable with the same name.
alias global_local {
set %foo 1
var %foo 2
echo -a %foo
unset %foo
echo -a %foo
unset %foo
}Which will produce the following result:
2
1/unset can only remove a local or global variable per each name specified, however it’s possible to remove both by specifying the variable name twice, for example:
alias global_local2 {
set %foo 1
var %foo 2
; unset both at once
unset %foo %foo
; will print empty quotes
echo -a $qt(%foo)
}Which will print empty quotes:
""No evaluation brackets are needed when unsetting dynamic variables:
alias dynamic_vars {
var -s %foo. $+ $calc(1+2) Test
var -s %bar. $+ $calc(1+3) Test
unset -s %foo. $+ $calc(1+2) %bar. $+ $calc(1+3)
}Which will produce the following results:
* Set %foo.3 to Test
-
* Set %bar.4 to Test
-
* Unset %foo.3
-
* Unset %bar.4Compatibility
