WRITE_ERROR: (STRTIME:PSTOP is not in common ### Fatal Error: PSTOP is not in common
It probably applies to any message of this kind, the name of the variable (PSTOP in this case), does not matter too much. This probably means you have an old version of the common block ($HATCOM) lying around. The cure would be:
CHECKER:checker> echo $HATCOM <-- check which it is CHECKER:checker> rm $HATCOM <-- delete the common block CHECKER:checker> createcom <-- create a fresh one
Of course this means that any fancy modifications you have made to the common block have to be done again.
