@.cdestr as varchar(20),
@.Indstr as varchar(20),
@.prdstr as varchar(20),
@.notpos as numeric,
@.nnotpos as numeric,
@.orapos as numeric
AS
begin
while (@.tempstr !=' ' )
loop
begin
@.orapos=CHARINDEX("OR", @.tmpstr)
if (@.orapos > 0)
begin
@.ntempstr=LTRIM(LEFT(@.tempstr, 2))
@.tempstr=Ltrim(mid(@.tempstr, (@.orpos+2))
end
else
begin
@.ntempstr=LTRIM(@.tempstr)
@.tempstr= ' '

@.notpos=CHARINDEX("NOT", @.tmpstr)
end
If @. @.notpos > 0 Then
@.nnotpos = LTrim(Mid( @.nnotpos, @.notpos + 3))
end
end

for( loop
GO

Unfortunately there really are quite a few errors in it. I suggest you start with a simpler version and then expand it as you get experience. A few corrections:it is not complete code snippet (the 'for' loop at the end is obviously incomplete, plus you have variables which you never use)
