DEFtype Declaration Statements
 
Use the BASIC statements DEFINT, DEFLNG, DEFSTR, DEFSNG, and DEFDBL to
declare the types for certain variable names. By using one of these DEFtype
statements, you can specify that all variables starting with a given letter
or range of letters are one of the elementary variable types, without using
the trailing declaration character.
 
DEFtype statements only affect variable names in the module in which they
appear. Remember a DEFtype statement affects all variables starting with
the given letter or range of letters.
