(Statement)
Declare a double-precision variable.
DEFDBL <variablename>[=<constant>][,<variablename>[=<constant>]...]

The double-precision variable range is from -1.7D+308 to 1.7D+308.
Specifying an equal sign and constant immediately following <variablename> performs initialization at the same time in declaration.
