DELETE_ITEM_EFFECT of Weidu v208

[plainab]

Could someone point me to the correct syntax and usage of DELETE_ITEM_EFFECT?
If I understand the WeiDU documentation it is a built in macro provided by Gort. It states:

DELETE_ITEM_EFFECT: deletes all extended effects with specified opcode from an item. This is a PATCH macro.

    * SET opcode_to_delete to the opcode of the effect you want to delete. Opcode of (-1) will match all effects.

For my needs I want to set it to -1 but I'm not sure of the exact syntax.
Do I write

Code: [Select]

DELETE_ITEM_EFFECT
 SET opcode_to_delete = -1Or do I do

Code: [Select]

SET opcode_to_delete = -1
DELETE_ITEM_EFFECT and is "opcode_to_delete" the built in variable name or what?

any help would be appreciated thank you.

Code: [Select]

SET opcode_to_delete = 0-1
LAUNCH_PATCH_MACRO DELETE_ITEM_EFFECT
No need to remind me that it's unintuitive

Thank you


And... uh... it is a bit unintuitive 

Oh... sorry... I wasn't supposed to remind you of that....
