The following routines were modified or enhanced in IDL 5.4. They may or may not affect cdfx.pro, but the routine certainly uses them. - Analysis routine: Roberts - Spawn. Called by DeviceClose, IDLMakeCDF, Pickdir and Getdirs - Xdisplayfile. Called by Pickdir and cdfx - Xfont - Xinteranimate - Xloadct - Xvaredit RCJ 09/00 Status log: CDFx is currently known to work on IDL versions 5.3-6.1. We never operationally ran CDFx w/ IDL 6.2 on 32-bit platforms - too many issues. CDFx is known to work w/ IDL6.3 64 bit on linux, MAC and PC. Some rumors about CDF and IDL6.3 64 bit NOT working correctly on a SUN - I believe CDF, IDL6.3 in 32 bit mode, works fine.
