[daip] curious sorting issue

[Walter Brisken]

I am using PCAT on a disk with 903 files (mix of UV and MA types).  I am
trying to get them sorted alphabetically and end up with some things out
of order.  Here is the relevent info:

AIPS: 31Dec99 from about March 20, 2000.

Inputs to PCAT:

>inp pcat
AIPS 1: PCAT:  Verb to list entries in the user's catalog (no log file).
AIPS 1: Adverbs         Values            Comments
AIPS 1: ----------------------------------------------------------------
AIPS 1: USERID        0                    User ID. 0 => current user
AIPS 1:                                      32000 => all users
AIPS 1: INDISK        7                    Disk drive #.  0 => all
AIPS 1: DOALPHA       1                    > 0 -> alphabetize listing
AIPS 1: SLOT          0                    > 0 -> start slot number
AIPS 1:                                    < 0 -> end slot number
AIPS 1:                                    = 0 -> all slots

Near the beginning of the output:

AIPS 1:  508 2179 B0149-16.99 .LCL023.    1 MA 20-APR-2000 10:54:25
AIPS 1:  509 2179 B0149-16.99 .LCL024.    1 MA 20-APR-2000 10:54:25
AIPS 1:  510 2179 B0149-16.99 .LCL025.    1 MA 20-APR-2000 10:54:25
AIPS 1:  511 2179 B0149-16.99 .LCL026.    1 MA 20-APR-2000 10:54:25
AIPS 1:  512 2179 B0149-16.99 .LCL027.    1 MA 20-APR-2000 10:54:25
AIPS 1:    9 2179 B0628-28.95 .FIX-I-.    1 UV 20-APR-2000 10:53:42
AIPS 1:  371 2179 B0628-28.99 .FIX-I .    1 UV 20-APR-2000 10:54:17
AIPS 1:   12 2179 B0736-40.95 .FIX-I-.    1 UV 20-APR-2000 10:53:42
AIPS 1:  309 2179 B0736-40.95 .ICL001.    1 MA 20-APR-2000 10:53:49

And somewhere about half of the way down the output of PCAT:

AIPS 1:  463 2179 B2327-20.99 .RCL016.    1 MA 20-APR-2000 10:54:24
AIPS 1:  464 2179 B2327-20.99 .RCL017.    1 MA 20-APR-2000 10:54:24
AIPS 1:  465 2179 B2327-20.99 .RCL018.    1 MA 20-APR-2000 10:54:24
AIPS 1:  466 2179 B2327-20.99 .RCL019.    1 MA 20-APR-2000 10:54:24
AIPS 1:  513 2179 B0149-16.99 .LCL028.    1 MA 20-APR-2000 10:54:25
AIPS 1:  514 2179 B0149-16.99 .LCL029.    1 MA 20-APR-2000 10:54:25
AIPS 1:  515 2179 B0149-16.99 .LCL030.    1 MA 20-APR-2000 10:54:25
AIPS 1:  516 2179 B0149-16.99 .LCL031.    1 MA 20-APR-2000 10:54:25
AIPS 1:  536 2179 B0149-16.99 .RCL001.    1 MA 20-APR-2000 10:54:25

Am I doing something wrong here?

Using the CATALOG verb I get the same problems.
