Hi,
I am using the database routines from the IDL Astronomy User's
library: (http://idlastro.gsfc.nasa.gov/contents.html#C3) on Mac OS X,
IDL version 7.1.
The following happens when I try to open two linked databases (the
yale_bs and yale_bs_rmks databases are available at
http://idlastro.gsfc.nasa.gov/ftp/zdbase/):
IDL> astrolib
% Compiled module: ASTROLIB.
% ASTROLIB: Astronomy Library system variables have been added
IDL> dbopen,'yale_bs_rmks,yale_bs'
% Compiled module: DBOPEN.
% Compiled module: ZPARCHECK.
% Compiled module: STRSPLIT.
% Compiled module: DBCLOSE.
% Compiled module: FIND_WITH_DEF.
% Compiled module: FIND_ALL_DIR.
% Compiled module: BREAK_PATH.
Attempt to subscript SBYTE with I is out of range.
IDL> dbhelp
% Compiled module: DBHELP.
% Compiled module: DB_INFO.
% Compiled module: TEXTOPEN.
% Compiled module: FILEPATH.
% Compiled module: DB_ITEM_INFO.
ENTRY HR CATEGORY REMARKS SPARES
------- Indexed Items ------
HR
----- Pointer Information ----
YALE_BS_RMKS.HR ---> YALE_BS
data base contains 9188 entries
% Compiled module: TEXTCLOSE.
IDL>
As you can see, only one is opened despite the two being linked.
I also noticed that using "/EXTERNAL" with dbcreate does not work on
Mac OS.
Does anyone has an idea what is going wrong. Is it an IDL bug on Mac
OS which treats binary files unexpectedly? Or is there an invalid
assumption in the database code?
Thanks and happy holidays.
Randolf

I'll let you know if I have more problems.

True, I only used it here so that people can easily try to reproduce
my problem.
Thank you,

I had fixed a problem with linked databases in dbprint.pro yesterday. But note the following:
1. The "linked databases" feature has not been used much, and I suspect that most of the remaining bug in the database software relate to linked databases.
2. I suspect that you are using YALE_BS catalog as a test database. I wouldn't recommend this 20 year old catalog now for most actual science.
