||The array count of the element values that make up the item. If present, the count is enclosed within square brackets “[ ]”. The count may be omitted, in which case the square brackets are also omitted. If count is omitted, then the length of the Data Item is implied by the value that follows.
The count specifies the number of value elements in the Data Item. For String formats (ASCII, Binary, JIS-8), count specifies the number of characters in the string. For Numeric formats (I1, I2, I4, I8, U1, U2, U4, U8, F4, F8, BOOLEAN), count specifies the number of values in the array. For simple scalar numeric values, count is usually “1”. For LIST Items, count specifies the number of items in the list.
Where count can range between known limits, it can also be specified as minimum and maximum counts separated by two dots. For example, a Data Item that is an array of ASCII characters (a string) with a valid length of 1 to 8 characters can be represented as follows:
The count specifier indicates the number of value elements in the array, which is not necessarily the same as the length of the Data Item.
