Are you by any chance saving repeatedly into files with the same name?
I seem to recall those versions of IDL had a problem with that under Open
VMS.

I cannot reproduce this problem. I just saved 3 variables into an XDR file on
a VAX/VMS 5.5-2 system using IDL 3.5.1:
IDL. Version 3.5.1 (vms vax).

Installation number: 2718.

IDL> a = 1.1
IDL> b=!pi
IDL> c = exp(4)
IDL> print, a, b, c
1.10000 3.14159 54.5981
IDL> save, a, b, c, file='[rivers.temp]test.xdr', /xdr
I FTPed the file to a SunOS 4.1.3 system and an SGI IRIX 5.2 system, both
running IDL 4.0.1, and read the XDR file in with no problem. The values of the
variables were correct.
IDL. Version 4.0.1 (sunos sparc).

IDL> restore, 'test.xdr'
IDL> print, a, b, c

Note that there IS a known bug with netCDF files written with IDL 3.5 and 3.6
on VAX systems. There is a utility program to repair the files.
