SECTION groups related paragraphs, terminated by next SECTION or end of program. PARAGRAPH is a named block of code, terminated by next paragraph/section. PERFORM SECTION executes all paragraphs within. SECTION needed for segmentation, PARAGRAPH for simple procedures.

ABEND deliberately terminates. EXEC CICS ABEND ABCODE('XXXX'). Causes transaction abend with code. NODUMP suppresses dump. CANCEL removes HANDLE ABEND first. Use for unrecoverable errors.

STOP RUN terminates entire run unit (all programs). GOBACK returns to caller; if main program, acts like STOP RUN. Use GOBACK in subprograms to return control. STOP RUN from subprogram ends everything unexpectedly.
