These data types and indirection symbols, .EXT32 and .EXT64 are 64-bit addressing functionality added to the EpTAL
compiler starting with SPR T0561H01^AAP. For more information, see Appendix E, “64-bit Addressing Functionality”
(page 531).
You cannot explicitly declare or change the address type of a pointer. pTAL determines the address
type based on the pointer declaration.
Every identifier you declare in a pTAL program has an object data type and an address type.
Table 50 (page 166) lists the address type for all pTAL constructs except simple variables. The
address type of a simple variable is the same as the address type of a pointer to data of the same
object data type as the simple variable.
