I was apparently wrong about this. Dick Jackson points
out to me in a private e-mail that he can include
EXECUTE and CALL_FUNCTION in run-time programs and they
work perfectly OK.

I'm embarrassed to say I didn't try this myself
when I wrote this advice, but based it on a recent
posting to this newsgroup from the usually reliable
Reimar Bauer, who wrote:

"there is a small amount of rules you should know.
[about run-time IDL]
* !PATH does not exist in runtime
* the filename of the routine have to be the same as
the calling procedure.
* EXECUTE won't work (e.g. read_ascii uses EXECUTE)
* nothing could be compiled but other compiled routines
could be loaded."

Here is a test program. Runs fine on Windows 2000 with
IDL 5.5 in run-time. Does anyone else have problems with
it?

**********************************************************
PRO RuntimeFeaturesTest
READ_JPEG, FILEPATH('rose.jpg', SUBDIR=['examples', 'data']), image
IF image[0] NE -1 THEN TV, /True, image
Wait, 1
Call_Procedure, 'Plot', RandomU(seed, 10)
Wait, 1
pixels = TVRd()
count = Call_Function('Total', pixels)
XYOutS, /Device, 100, 100, 'Total of pixels: '+StrTrim(count, 2)
Wait, 1
ok = Execute('Erase')
Wait, 1
END
**********************************************************

IDL> runtimefeaturestest
IDL> Resolve_All
IDL> Save, File='runtimefeaturestest.sav', /Routines

What do you make of this, Reimar?

Cheers,

David
