Processing considerations for 32-bit and 64-bit data types

OpenEdge supports an existing or new 32-bit INTEGER data type defined in ABL. However, the internal bit size for an INTEGER data type will automatically expand from a 32-bit field size to a 64-bit field size to accommodate larger values. And, in most situations, this expansion also supports the option to convert a database column from a 32-bit INTEGER to a 64-bit INT64 without performing a dump and load. Refer to the following sources for additional language details about INT64:
