operands
Constant All binary data
(16-bit data) and binary data
within a range
All BCD data
and BCD data
within a range
Constant All binary data
(32-bit data) and binary data
within a range
All BCD data
and BCD data

Specifying Text Strings
Method
Text strings Text is stored in ASCII (1 byte/
character excluding special
characters) starting with the
lower byte of the lowest word
in the range.
If there is an odd number of
characters, 00 (NULL) is
stored in the higher byte of the
last word in the range.
If there is an even number of
