Reply with quote

Using ICETOOL, I want to use only a couple of columns on a DISPLAYed Report to show the value of flag types fields which are only 1 byte long.

It looks like the default minimum column width for character type fields is 20 bytes, even if the literal specified in the HEADER is smaller (I don't understand why this is the case? - I would think if the length of the HEADER literal is greater than the associated defined field length, the printed report would use the Header's length as the Column width for the Character type field).

At any rate, though I many ways to change the printable length of numeric fields, (i.e. 'ON(p,m,f,formatting)') -- I haven't found anything to help me get rid of the extra column width for 1-byte flag type of fields.

Thanks in advance for any help!

I believe the BLANK operand will give you what you want.

DISPLAY BLANK ...

For sure ...
and frankly speaking, I very much appreciate Frank's willingness to do all he does for us.

Let's be Frank (oh, don't I wish!) - he's a veritable treasure to the mainframe user community.

This is a DFSORT/ICETOOL job so the control statements are in //TOOLIN, not in //SYSIN, and consists of the DISPLAY operator statements.

If you're not familiar with DFSORT and DFSORT's ICETOOL, I'd suggest reading through "z/OS DFSORT: Getting Started". It's an excellent tutorial, with lots of examples, that will show you how to use DFSORT, DFSORT's ICETOOL and DFSORT Symbols. You can access it online, along with all of the other DFSORT books, from:
