1797.0. "General discusion on %BASIC-E-STACKOVF ... " by CSC32::D_SANFORD () Tue May 06 1997 17:34

  A customer modified an old application giving the above error, but claims
  he did not add any dynamic variables, instead he changed the size of an
  item in a MAP from 200 to 220 bytes...  I cannot duplciate this and 
  suspect there is more to it.

  CLT::VAX_BASIC, note 685.4/14 suggest that making a static dimension
  (DIM X(100,2000), stored in PSECT or stack) into a dynamic dimension
  (DIM X(y%,z%)) to get around this problem.  Can increasing a MAP 
  cause this error since it uses a PSECT?

  The the BASIC User Guide:  

    STACKOVF, stack frame overflow for variables

        Explanation:    ERROR-The program requires too much
        space for dynamic variables.

        User Action:    Reduce the number of dynamic variables
        or place some of the variables in a MAP or COMMON.

  As you can see the action above contradicts the use of a dynamic
  dimension...  What is the easiest way to deal with this?  If possible
  can you tell us what the limit is and how elements are counted?
