SQL supports long SQL names and short system names.
If the "long" name is shorter or equal 10 characters, SQL and System Names
are identical.
For longer names the short name is automatically determined, taking the
first 5 characters of the long name and adding a 5 digit running no.
If you do not want the system name to be automatically created it is
possible to set it manually (even though the SQL/Long name is shorter or
equal 10 characters).

Rory,
I just had to try it. <g>
Yep - when I run this
crtpf file(qtemp/"a.b.c") rcdlen(1)
wrkobjpdm shows -
Object Type Attribute Text
"a.b.c" *FILE PF-DTA
Then when I run this
runqry () qtemp/"a.b.c"
I get this
....+..
"a.b.c"
******** End of report ********
Never heard of this before. (and, cant think of when I'd need it)

It gets even goofier with SQL DDL tables:
create table mylib."this is my table oh yes it is" ("column name with
spaces" for colname char(5))
The 10-character object name is rendered as "this0001". Running DSPFFD
against the 10-character name shows a field of COLNAME, with an alternative
name of "column name with spaces". Running DSPFD against the 10-character
object name shows an alternative file name the same as the SQL table name.
The old admonishment, "just because you can do something doesn't mean you
should do it", comes to mind.
