(12C) Does a STO pop the stack or not?

[rprosperi]

While there are several inconsistencies between 12C and 12CP, I do not believe there are any between the various mfg. versions of the 12C Gold, but could be wrong.

For the 12CP, see this old thread too:

https://www.hpmuseum.org/cgi-sys/cgiwrap...ead=190342

While the 12C Gold and 12CP are broadly compatible, the small details in these articles show that they cannot be considered compatible for any arbitrary program without testing. Note that some of the techniques discussed in the threads (e.g. inserting extra Enter statements) can make programs behave the same on both models, but doing so adds extra commands making it longer, and can also appear confusing to other folks ("why is there an extra Enter here?").
