The DEFSTR statement defines all designated undefined variables AS STRING variables instead of the SINGLE type default.


Syntax: DEFSTR firstletters


  • The variable first letters can be from A-Z or any other range.
  • You can also use commas for specific undefined variable first letters.
  • Variables DIMensioned as another variable type or that use type suffixes are not defined otherwise.
  • 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.


Example: DEFSTR A-S, Z
