RE: [wp34s] Is it possible to call an XROM from another one?
Well, now I have a working inverse Gamma in XROM (not very tidy, as I also have modified the lambert_w code to place some hooks there). But I still have some doubts about xIN/xOUT workings.
I've read that executing xIN creates a "local" 8 levels stack, a "local" return stack & changes to DP. But, does it also create a set of 16 local flags? If so, will a subsequent LocR "hide" such flags? (I think the answers are {YES, NO}, but not sure.) Suppose also that an XROM function executes xIN, then, inside such function, there's a LocR and a GSB, and this second subroutine ends with RTN. Will such RTN "free" the LocR'ed registers? (I think {NO}, they are freed by POPLR or xOUT in the calling XROM function.) In an XROM function calling (via GSB) other subroutines, can LocR be nested? (I have no idea.) Thanks. |
