*+121210 problem with I50
2
This evening during MI tune-up before Pbar transfer, ops used I50 smooth program to check the orbit. The program malfunctioned and sent out changes even though ops had moved the arrow to "calc predicated orbit". After this we were unable to get beam to circulate. The program saved the vertical smooth data instead of the horizontal and showed that vertical changes had been made when, in fact, horizontal changes had been made. Ops restored the vertical changes that the program showed, but to no avail. In the end restoring the horizontal smooth change back to a change sent out earlier on the shift did the trick.

Diagnosis: wehen changing event read in the 'active' setup parameters for the event that include 'plane' and 'stop_step'. 1) 'cor->plane' have not updated alongside with 'spars.plane'. Both of them are used directly in routine corr6_send so happened send to hori plane but writen to vert. 2) spars.stop_step took new value but didn't update

the display.

Fix: add call to init after changed event: 
9
1) basically set cor->plane = spars.plane. 
10
2) update 'stop_step' display.

Note: Now when init or changing event 'active(i50setup record id=1)"
13
setup parameters are read in. 'cor->' must be made consistant with 'spars' read in. And parametrs must be re-displayed.

The 'active' file is changed only through cmd 'Recall' from saved
15
files.
