Field help (ATBCODTYP)

The field type is defined here, which characterize the entry format (numeric, any characters, date...) and the coherence controls (reference to a table for example).

The principal generic types that exist :

A : Alphanumeric
C : Short integer
L : Long integer
DCB : Decimal
D : Date
M : Local menu
MM : Local menu with filter
ACB : clob
ABB : blob

But many other predefined types exist. They often make reference to an annex table (currency, country...). A dedicated dictionary is used to described them and they can be selected using the key that is used to obtain the list.
