Complicated Healing Macro Fun

Ever since I got my new PC I've been meaning to finish putting my UI and macro's back the way I had them on my old one. As I had a nice healing boost from my new mace and trinket last night I decided it really was time to at least restore my healing macro's.

So with a bit of a reminder (read: plagiarism) from Mystic Chicanery I rebuilt them. Ahem, just as we were about to make the first pull.

What I had was a HL(6) and a FoL macro doing the same thing. I Manually weave in the HL(6) in every 5-7 casts to keep up Light's Grace and a HL(11) macro for those "Oh Shit!" moments.

HL(4) and FoL Macro

#showtooltip Flash of Light
/script UIErrorsFrame:Hide();
/use Essence of the Martyr
/use Ribbon of Sacrifice
/cast [target=mouseover] Flash of Light
/script UIErrorsFrame:Clear();UIErrorsFrame:Show();

Big Holy Light Macro

#showtooltip Holy Light
/script UIErrorsFrame:Hide()
/cast Divine Illumination
/cast Divine Favor
/cast [target=mouseover] Holy Light
/script UIErrorsFrame:Clear();UIErrorsFrame:Show();

Now what I am thinking of doing is:

a) Incorporating Rohan's cast sequence (an excellent post which I read yonk's ago but never got round to implementing) into the FoL macro and then I can lose the HL(4) button altogether. Replacing the /cast [target.... line with:

/castsequence [target=mouseover] reset=10 Holy Light(Rank 6), Flash of Light, Flash of Light, Flash of Light, Flash of Light, Flash of Light

b) Incorporating Libram swapping into macro after the cast. I discussed this with Nibuca quite some time ago and never implemented it. A simple choice of one of these should suffice. It can go after the cast as it is equipped during the cast time apparently.

/equip Blessed Book of Nagrand
or
/equip Libram of Souls Redeemed

c) Swapping Divine Illumination into the FoL macro for increased mana efficiency.

d) Incorporating targettarget and if friendly into the cast sequence macro

e) Having 2 FoL/HL macros. One with FoL(6) and HL(4) for very mana efficient healing and a FoL(7) and HL(6) for when things get more hectic.

You'll notice the /script lines. These stop error messages being shown on the screen when trinkets are not available for use and when DF and DI are not ready yet, unfortunately you still hear the messages. If you know a way to stop the messages being said by your avatar please let me know.

The trouble is you are limited to the number of characters you can have in a macro, something like 250.

Just by doing a,b and c above my macro now becomes:

#showtooltip Flash of Light
/script UIErrorsFrame:Hide();
/cast Divine Illumination
/use Essence of the Martyr
/use Ribbon of Sacrifice
/castsequence [target=mouseover] reset=10 Holy Light(Rank 6), Flash of Light, Flash of Light, Flash of Light, Flash of Light, Flash of Light
/equip Libram of Souls Redeemed
/script UIErrorsFrame:Clear();UIErrorsFrame:Show();

This is 360 characters and I haven't even put in 5 x (Rank 6)

Now I have read somewhere about getting round this by calling a macro from a macro, but I can't find it anywhere at the moment.

Ideally I will have 2 separate macro's just doing the 2 separate castsequences as described in (e) and then calling one normally and the other with a modifier such as shift or alt.

Can someone please tell me how to do it? plxkkthxbai
