Yes, these same limitations re: nested/recursive calls will be maintained in the DM32. There are multiple reasons, but limited memory is the main driver.

Your presentation (thank you) mentioned 1.5 megabyte of RAM...the 32SII manual claims 33.5 bytes are needed for solve, 140 bytes are needed for integrate and each use one pending subroutine return. Since we didn't have access to the solve or integration scratch variables in the original calculator (did we?) I would think using a few more bytes of RAM and a pending subroutine would be a worthwhile tradeoff for an extra nested or recursive call. I'm ignoring the other multiple reasons for not implementing this option and would be happy to get a modern hardware 32SII with 384 bytes...but I won't turn down the extra memory. Thanks again for your presentation.
