All righty, then... for those who missed the last installment of 'As the
Captain Codes' I had a utility program that was blowing up. The guts of
it were:

MOVE CORR REC-A TO REC-B

... and if there were bad numerics in REC-A the program would blow up and
dump with a S0C7.

Folks have stated that there are facets of the Language Environment which
will 'trap' a statement which would normally cause an ABEND and allow
processing to be resumed... this is something with which I am totally
unfamiliar.

Being (echo chamber on) CCCAAAAPPPTTAAAIIIINNN... COBOL... OBOl... OBol...
Obol... Iiiiii... leeeearrrrnnnn... (echo chamber off) I learn best from
reading code. Is there someplace that someone might point me towards
where I can find simple code, along the lines of:

WORKING-STORAGE SECTION.
01 STUFF.
    05 FILLER PIC XX VALUE SPACES.
01 FILLER REDEFINES STUFF.
    05 FLDA PIC 9.
    05 FLDB PIC 9.

PROCEDURE DIVISION.
                                                                 
    SUBTRACT FLDB FROM FLDA.
    DISPLAY ' MADE IT THROUGH, NYAH NYAH NYAH!'.

... and say 'In order to execute the DISPLAY you'll have to...'?

Thanks much.
