The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

DRAW Statement - Differences from BASICA
 
    ■ Some DRAW statements that are allowable in BASICA programs require
      modification when used with the BASIC compiler. Specifically, the
      compiler requires the VARPTR$ form for variables. For example, the
      BASICA statement
          DRAW "TA = Angle"            ' Angle is a variable.
      must be changed for the BASIC compiler as follows:
          DRAW "TA =" + VARPTR$(Angle)
 
    ■ The BASIC compiler does not support the BASICA
          Xstringexpression
      command. However, you can execute a substring by appending the
      character form of the address to X. For example, the following two
      statements are equivalent. The first statement works when within the
      environment and when using the compiler, while the second works only
      within the QBX environment.
          DRAW "X" + VARPTR$(A$)
          DRAW "XA$"
