The DEFINT statement defines all designated undefined variables AS INTEGER variables instead of the SINGLE type default.


Syntax: DEFINT firstletters


  • The variable first letters can be from A-Z or any other range.
  • You can also use commas for specific untyped variable first letters.
  • Variables DIMensioned as another variable type or that use type suffixes are not defined otherwise.
  • DEFINT allows users to create larger graphical arrays up to the integer limits.
  • The maximum value of a signed Integer variable is 32767. Minimum is -32768.
  • UNSIGNED Integer values from 0 to 65535. See _DEFINE
  • Qbasic's IDE may add DEF statements before any SUB or FUNCTION. QB64 will change all variable types in subsequent sub-procedures to that default variable type without giving a "Parameter Type Mismatch" warning! If you do not want that to occur, either remove that DEF statement or add the proper type statements to subsequent procedures.


Examples:

DEFINT A-Z
DEFINT A-D, Z
DEFINT A, I, O
