On my Mac copy of IDL, the CD came with "working" example of the call_external and the c code. I basicly built my external c routines by building on the ones supplied. I suspect that the NT version of IDL also supplies call_external examples. Regards Patrick Ford, MD Department of Radiology Baylor College of Medicine pford@bcm.tmc.edu
