DEFtype, Type ID or type-specifier (?%&!#$), or AS ... required - A variable with no type declaration was found and no DEFtype statement (such as DEFINT) was found. The compiler was unable to identify the type of variable indicated. The misspelling of variable names commonly causes this error. The DEFtype statement may not be supported in future editions of PowerBASIC. Use explicit declarations wherever possible to maintain future compatibility.
