CSData/CSSafety

Does ReleaseGroup(g) also use a space?

???? sorry I don't' understand what you're asking

When ReleaseGroup(g) called, I see the MAX_HANDLE error.

You are probably leaking handles and its gone over the limit. Also CSData/CSSafety is out of date. If you wan't something more modern use HSAS

Aren't they decapricated anyway?

Deprecated, yes.

If you need ReleaseGroup then it's very likely you're using groups wrong.

Are local groups a nono then?

Pretty much. You always use a global group for enums, and for spellinstances that need a group you recycle groups along with the spell struct index.

Can you create/find an example of how it should be done?

Example of what? Global groups or group-per-struct recycling?

HSAS seems less modern than CSData

Looks can be decieving

Anyways it used to be a lot longer until the array size got extended in vJASS
