hi IDL wizards,
(first I apologize for my bad english)
I'm running IDL scripts communicating with fortran-programs
(f77, i.e. calculation of geomag.field/IGRF) by bidirectional pipes
created from 'spawn' command (with keyword 'unit')
this works fine for years. now (with IDL 5.3) I found the spawned program
vanished without any message, more or less immediately -- and
the next (first) 'readf, unit, buf' fail, of course -- or, worse,
IDL terminates with 'segmentation fault'.
I found that this 'segmentation fault' depends on
the way I'm assembling the string given into the pipe.
only if the string is created by a simple dummy = 'something' statement
printing/writing from pipe succeed.
after downgrading to 'IDL 5.2' all is working fine again.
I can't belive, that THIS usefull feature (one benefit
of IDL over 'matlab'?) is broken. kkkkrrrrxxxxxxx....!
I searched 'dejanews' and found some articles about this (or similar)
subject, but I found no workaround and remain hopeless.
have I to stick on version 5.2 forever?
(my environment: sparc, solaris 2.6 + 2.7 and enough memory...)
thanks in advance for hints.
best regards,
martin rother.

An excellent time to jump ship to emacs+IDLWAVE mode. Expect the announcement
of a major update with several exciting new features in the near future... and
prepare to do things that IDLDE users could never dream of.
