that may be one of the reason...
but i am not using backticks for all the commands...
today my program hung at following location
system "DTSRun \/S \"test_box\\TSQL02\" \/N \"Weekly
mfdf Cubes\" \/V
\"{FE3888AE-3ABB-4A4C-84CF-EB12BF466177}\" \/L
\"$dts_err_file\" \/W \"-1\" \/E";
Here i am not using any backticks ?
i am suspecting do we need to handle any signals in my
program ?
thanks
