Now about problems. Everything works fine in AMS 1.xx, but AMS 2.xx forbids the use of ASM programs in expressions. So, in the above example, 'add(2,3)' will work perfectly, but '5+add(2,3)' or even 'add(2,3)->a' will not. This stupidity makes returning values mostly useless. What to do? Unfortunately, I can't do nothing from the TIGCC itself, because an ASM program will not be executed at all if AMS 2.xx detects its presence in an expression. However, there is a solution: it is possible to make a resident program which will intercept such "stupid" behaviour of AMS 2.xx and to allow executing ASM programs in expressions. Such interception is already implemented in the latest versions of DoorsOS, Universal OS, PreOS and KerNO (but not in TeOS). So, if you have installed a fresh release of DoorsOS, Universal OS, PreOS or KerNO, everything will work OK even on AMS 2.xx. There is also a TSR called IPR which intercepts only this error and the "ASAP or Exec string too long" error available at Cyril Pascal's (Paxal's) web page for those who don't want to install a full-featured kernel. But for HW2 calculators, the HW2 AMS 2 TSR support (h220xTSR) needs to be installed before IPR. This does not mean that your program must be compiled in "Doors" mode: it may be a "nostub" program, but DoorsOS, Universal OS, PreOs, KerNO or IPR must be present on the calculator (to intercept stupid behavior of AMS 2.xx). To conclude: if you have AMS 2.xx and if you want to use "returning a value" feature, you must have installed DoorsOS, Universal OS, PreOs, KerNO or IPR. If you are a programmer, please note this fact in the documentation of any program which uses this feature!
