NAME
  DEFtype Statements

SYNOPSIS
  DEFINT letterrange [,letterrange]...
  DEFLNG letterrange [,letterrange]...
  DEFSNG letterrange [,letterrange]...
  DEFDBL letterrange [,letterrange]...
  DEFSTR letterrange [,letterrange]...
      o letterrange    A letter or range of letters (such as A-M). QBasic
                       sets the default data type for variables, DEF FN
                       functions, and FUNCTION procedures whose names begin
                       with the specified letter or letters as follows:
                       Statement    Default Data Type
                       ---------    -----------------------
                       DEFINT       Integer
                       DEFLNG       Long integer
                       DEFSNG       Single precision
                       DEFDBL       Double precision
                       DEFSTR       String
      o A data-type suffix (%, &, !, #, or $) always takes precedence over a
        DEFtype statement.
      o Single-precision is the default data type if you do not specify a
        DEFtype statement.
      o After you specify a DEFtype statement in your program, QBasic
        automatically inserts a corresponding DEFtype statement in each
        procedure you create.

DESCRIPTION
  Sets the default data type for variables, DEF FN functions, and FUNCTION
  procedures.

  Example:
      DEFDBL A-Z
      a = SQR(3)
      PRINT "Square root of 3 = "; a
