Happy New Year !!!

I am working on  a AIX  machine with R  Version 1.9.1   on AIX 5.2 ML-3. 
The perl.rte fileset is at 5.8.0.0 

The following line is a part of a cgi script:

 open(T, "| /usr/local/bin/R --silent --no-save < /var/tmp/lll.input 
>/var/tmp/messages.out");

The contents of  file  /var/tmp/lll.input  are as follows:

tts.console(file="/var/tmp/wi.lll.dat",pfile="/var/tmp/wi.lll.ps") 

When the cgi script is executed  /var/tmp/wi.lll.ps is not generated.

However I invoke 
 /usr/local/bin/R --no-save --min-vsize=20M --min-nsize=1000k < 
/var/tmp/lll.input 

from the command line, it executes correctly and  also generates the 
post-script file /var/tmp/wi.lll.ps

Are there any know issues with R working through UNIX pipes? 

Any help/hints offered is gratefully acknowledged.

Regards,

Sridhar
