DT Define Ten-byte Unit MASM Directive
[name] DT initialvalue,,,
Allocates and initializes one or more ten-byte units of storage.
Notes: The optional name argument causes the assembler to
create a variable whose offset value is equal to the
current location counter value. The variable will be of
The initialvalue argument may be any of the following:
* integer expression (i.e. 12334d)
* packed decimal (i.e. 0123456789)
* 1 or 2 character string constant (i.e. 'gh')
* encoded real number (i.e. 2F0000000000000r)
* DUP operator (i.e. 10 dup (?))
* question mark (?) (i.e. 0,1,?,2)
The ? causes the assembler to leave the initial value
undefined. To specify more than 1 initial value,
separate them with commas.
String variables of type TBYTE must not consist of more
than 2 characters. The last character is placed in the
low-order byte of the word, and the first character (if
there are 2 characters) or 0 (if only 1 character) is
placed in the next byte. Zeros pad the rest of the
Constants with decimal digits are treated as packed
decimal numbers, rather than integers. In order to
specify a constant as an integer with DT, append a
letter specifying the number system to use to the end of
the number. For example, append 'D' for a decimal
number or 'H' for a hexadecimal number.
