Re: reference to variable fields in IBM copybooks

One specific item of caution -- If you're working with
QIBM_QZDA_SQL2 with the ZDAQ0200 format, ensure that you do NOT use
SQL-STATEMENT-TEXT2-LEN as your length field if it has a value
greater than 1024. You might want to declare a different field and
either move SQL-STATEMENT-TEXT2-LEN or 1024 into it depending on
whether SQL-STATEMENT-TEXT2-LEN is too big. Also, decide how to
handle a case where length is zero. Eventually you WILL run across
both conditions (among various interesting others).

Funny you should mention these. I had not yet updated the code to handle
len=0 or len>1024, and I came in day to see the dev system had experienced
each of these problems overnight.
