Not sure if this is much help, but it was fun to compile and run. Here's
the output from:
IDL Version 6.0, Microsoft Windows (Win32 x86 m32). (c) 2003, Research
Systems, Inc.
Average1 = 3.3160019e-006 s
Average2 = 3.1799984e-006 s
IDL Code Profiler reports:
Module Type Count Only(s) Avg.(s) Time(s) Avg.(s)
TESTROUTINE1 (U) 250000 0.417654 0.000002 0.417654 0.000002
TESTROUTINE2 (U) 250000 0.416161 0.000002 0.416161 0.000002
