You can create new, empty<br />

INFO tables in <strong>ArcCatalog</strong>. The<br />

table’s name must be<br />

32 characters or less, while<br />

column names must not exceed<br />

16 characters in length. Columns<br />

are defined using<br />

standard ArcInfo data types<br />

such as Binary. The input width<br />

is the maximum number of<br />

characters or bytes used to<br />

store the column’s values. For<br />

numeric columns, the width<br />

must be large enough to<br />

accommodate the decimal point<br />

and negative sign. The display<br />

width is the number of spaces<br />

used to display values in<br />

ArcInfo Workstation; for<br />

decimal values, the display<br />

width should be one space<br />

greater than the input width to<br />

account for the decimal point.<br />
