Running command inside awk

Hi,
I have a awk script to read a CSV file.
After reading the values i want to call a executable (nameely call_it) with the values what i read from the scv file.
I dont want to use system command inside the awk.
Is there any other way to run the executable from the awk script

Thanks
Raghuram

this example may helps u:

> echo|awk '{"date"|getline;print}'
