Examine the contents of registers 14 and 15. If register 15 has a value of 0, then the probable cause is that a routine doesn't exist and a branch was made to location 0. This would indicate a link-edit failure. Examine the contents of register 14 to determine the point at which the branch was made. Also examine the linkage editor map for any unresolved references reported by the linkage editor.
Another possible cause is a routine branched to some unintended location, such as a conflict in addressing mode between the calling and the called routine, or any other program error that branched to the wrong location.
