I created a variable $outputFileName.

The value of $outputFileName is /home/myung/ns-allinone-2.28/ns-2.28/COMP_TC/result/RW/K9-RW.

Except the file name itself (K9-RW), all directories exist.

I want to create a file called "K9-RW" and write to it.

So I did programming as follows.

sysopen(OUTPUT_HANDLE, $outputFileName, O_WRONLY|O_APPEND|O_CREAT, 060
+0) or die "        Can't open $outputFileName : $!";

But I got an error like the below.

[myung@mirim script]$ conn.pl 100 1 2 9
Can't open /home/myung/ns-allinone-2.28/ns-2.28/COMP_TC/result/RW/K9-R
+W : No such file or directory at ./conn.pl line 128.
