DEFSNG
(Statement)
Declare a floating-point variable.
DEFSNG <variablename>[=<constant>][,<variablename>[=<constant>]...]
This statement declares the variable specified by <variablename> as a floating-point type (single-precision variable of type real).
The floating-point variable range is from -3.4E+38 to 3.4E+38.
Specifying an equal sign and constant immediately following <variablename> performs initialization at the same time in declaration.
More than one variable name can be declared at a time by delimiting those names with commas.
