WoW:API CastSpell

CastSpell -Documentation by Lorrick-

Returns information about the specified spellbook tab.

CastSpell({spellID}, {spellbookTabNum});

Arguments
( spellID )
spellID
Integer - Spell ID.
( spellbookTabNum )
spellbookTab
Integer - Spellbook tab to retrieve information for. Valid values are 1 through MAX_SKILLLINE_TABS(8).

Returns
??

Example
SPELLBOOK_TAB_GENERAL = 1;
CastSpell( 1, SPELLBOOK_TAB_GENERAL );


Result
Casts the first spell listed on the general tab of the spellbook.

Description
Cast specified spell.

Note
Just use SpellBookFrame.bookType as the spellbookTabNum for any spell. the id is then just counted from the beginning through all tabs. the CastSpell function can only be used in OnClick functions. Another way is to use it in a Slash command and then the user makes a macro out of it and clicks on it. (seems WoW only allows this when a mouseclick / key input has initiated it)
