some precompiler directives

#forpair v_id, v_value = (test=12,ab=33), v_count
similar to #for, but allows pairs of information
**************************
#defineglobal
extends the lifetime of the #define to the end of the compile unit
**************************
#definegroup
extends the lifetime of the #define to the end of the compile module
form
entity
field
**************************
 

for a clearer to handle directives.

You see directly the pair and do not have 2 lists where you have to take care the positions are kept (current way to handle pairs)

#definegroup and #defineglobal to define in a trigger (<LPMX>) which can be reused in entities or fields without toggle to the <DEFN> trigger 

Once again, easier handling, easier maintenance, global #defines can be set in the context of the other code instaed of jumping back and forth.

Some frameworks I saw request a "#define xyz" (currently in <DEFN>) if you want to specify a "user exit" in (LPMX).
