RE: Does SST does not support Variable length field in logical ?

["Vengoal Chang" <vengoal@xxxxxxxxxxx>]

Thanks your help,
Now I am testing the Tracking Triggers  by Doug Eckersley from
Mcpressonline
  http://www.mcpressonline.com/mc?1@xxxxxxxxxxxxxxxxx@.6ae73ce8 , and I
could not compiled LF which contain system table variable field. I can
test your suggestion. Do you have any other idea ?

Best regards,

Vengoal

Unfortunately, there are no fixed length fields for these things in this

file, as far as I can tell. Could you redefine the fields as character
in 
the logical, then SST those new fields? This would be like a logical
that 
redefines packed fields as zoned.

BTW, is there a reason not to use the already-existing view in QSYS2? Of

course, that means using SQL, more than likely, and it also has the
VARCHAR 
fields. Vengoal, can you say more about the need for getting this 
information? Will you be reading it in a program, or creating a report
from 
it? If the latter, I strongly suggest using QM forms and QM queries. If
the 
former, RPG can use variable length fields, or you could use SQL in the 
program easily.

An odd thing about the file in question is the use of allocated length.
The 
varchar fields for file and library have an allocation of 10, which
makes 
sense. But the fields for program and library have allocation of "None"
- 
is that the same as 0? But maybe there's no point in worrying about this

when there are many other fields with no allocation, because that
already 
forces reading the auxiliary space where variable data is held.

Also, there are a couple CLOBs, thousands of bytes long, for some path 
names, best as I can tell on short notice.
