ircII help - foreach

Usage: FOREACH <structure> { }

       FOR <structure> { }        FOR (<commence,) { }   This causes <commands> to be executed once for each   element in the structure. The aliases inside the {}   are not expanded until execution unless the leading {   is quoted like \{   The 2nd style of FOR allows C-style for loops.   Here are a couple examples of basic foreach commands.     assign blue.1 one     assign blue.2 two     assign blue.3 three     foreach blue ii { echo $ii $blue[$ii] }   will return     1 one     2 two     3 three   foreach can also be imbedded such as in the following example.     assign blue.1.1 one one     assign blue.1.2 one two     assign blue.2.1 two one     assign blue.2.2 two two     alias showblue {       foreach blue ii       {         foreach blue.$ii jj         { echo $ii $jj $blue[$ii][$jj]         }       }     }   And /showblue returns..     1 1 one one     1 2 one two     2 1 two one     2 2 two two

Note:   When using this format the {} in the foreach must be on separate   lines by themselves. This is true for if and while as well.

  Notice that variable names 'ii' and 'jj' were used. Any name can   be used for the index but keep in mind that single letter vars can   interfere with the built in single char vars. See ALIAS special
