The CrossWorks assembler provides a number of built-in or pre-defined data types. These data types correspond to those you'd find in a high-level language such as C. You can use these to allocate data storage; for instance the following allocates one byte of data for the symbol count:

count   DV      BYTE

The directive DV allocates one byte of space for count in the current section and sets count's type to BYTE.
