give this a go:

create proc proc2
(
@var1 int output
)
as
begin
set @var1 = 5
end
go

create proc proc1
as
begin
declare @outputval int
exec proc2 @var1 = @outputval output

select @outputval
end

this does not work.
it keeps on saying

Procedure or function 'proc2' expects parameter '@var1', which was not supplied.

Your procedure save_engine_clause_group has two params, but you're only passing in the first one.  You'll need to pass in an XML param and then the 2nd param followed by the OUTPUT statement

so if i do something like this
exec save_engine_clause_group ClauseGroupXML,@ClauseGroupID, @var = @outputval output

it says too many arguments

try this instead:

exec save_engine_clause_group
@ClauseGroup  = @ClauseGroupID,      
@EngineClauseGroupID = @outputval output
