I had to look up the "CONTINUE" statement. In 25 years I've never used
it,
and don't even remember seeing it used. Now I know what it does I think
it
should be banned.

I use CONTINUE all the time when processing
records that must meet multiple conditions in a loop. This way my code doesnt
look like 'flying geese'. I will write:
LOOP WHILE READNEXT ID
READ RECORD
FROM FILE, ID ELSE CONTINUE
IF RECORD<FLD.1> NE COND1 THEN CONTINUE
IF
RECORD<FLD.2> NE COND2 THEN CONTINUE
IF RECORD<FLD.3> NE COND3 THEN
CONTINUE
RECORD<FLD.4> = 'PROCESSED'
WRITE RECORD TO FILE, ID
REPEAT
instead of:
LOOP WHILE READNEXT ID
READ RECORD FROM FILE,ID THEN
IF
RECORD<FLD.1> EQ COND1 THEN
IF RECORD<FLD.2> EQ COND2 THEN
IF RECORD<FLD.3> EQ COND3 THEN
RECORD<FLD.4> = 'PROCESSED'
WRITE RECORD TO FILE, ID
END
END
END
END
REPEAT
