- DEFSTR letter[-range]
- The variable starting 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.
- _DEFSTR sets the type of all variable names with the starting letter(s) or letter ranges when encountered in the progression of the program(even in conditional statement blocks not executed and subsequent SUB procedures).
- Qbasic's IDE may add DEF statements before any SUB or FUNCTION. QB64(like QB) will change all variable types in subsequent sub-procedures to that default variable type without giving a "Parameter Type Mismatch" warning or adding the proper DEF statement to subsequent procedures! If you do not want that to occur, either remove that DEF statement or add the proper DEF type statements to subsequent procedures. May also affect $INCLUDE procedures!
Example: DEFSTR A-S, Z
