Data Type Aliases The compiler accepts the following aliases for the listed data types:

Data Type Alias

INT INT(16)

REAL REAL(32)

FIXED(0) INT(64)

Storage Units Storage units are the containers in which you can access data stored in memory. The

system fetches and stores all data in 16-bit words, but you can access data as any of the

following storage units:

Storage Unit Number of Bits Data Type Description

Byte 8 STRING One of two bytes that make up a word

Word 16 INT Two bytes, with byte 0 (most

significant) on the left and byte 1 (least

significant) on the right

Doubleword 32 INT(32), REAL Two contiguous words

Quadrupleword 64 REAL(64), FIXED Four contiguous words

Bit field 1–16 UNSIGNED Contiguous bit fields within a word

Bit field 17–31 UNSIGNED Contiguous bit fields within a

doubleword

In TAL, a word is 16 bits regardless of the word size used by the system hardware.
