DefSng start_letter[-end_letter ][, ...]

start_letter
end_letter

DefSng specifies that variables and arrays which aren't declared with a data type - or not declared at all - are implicitly declared of type Single if the first letter of their names matches a certain letter or lies within an inclusive range of letters.

This will make sNumber and yNumber a Single-precision decimal number since it is in the range of s-z.
