Date value whose internal representation is 34335.0. Any valid date can appear with #'s. Date literals are interpreted at execution time using the locale settings of the host environment. To ensure that date literals are correctly interpreted for all locales, use the international date format:

#YYYY-MM-DD HH:MM:SS#

Constant Folding

The Basic Control Engine supports constant folding where constant expressions are calculated by the compiler at compile time. For example, the expression

   i% = 10 + 12

is the same as:

   i% = 22

Similarly, with strings, the expression

   s$ = "Hello," + " there" + (46)

is the same as:

   s$ = "Hello, there."
