First off, define what you mean by "non blank lines of code".
Some questions to consider:
/What/ code? (shell script code? java? c++? c? perl? awk? TCL? each
language has it's own concept of what a "line of code" consists of)

Do compound statements count as one line or multiple lines? (Consider
what the C " { something(); something_else(); result=third_thing(); } "
means; is this one, three, four, or five lines of code?

How do you distinguish a "line of code" from other, extraneous lines?
(How do you handle comment lines, for instance?)

How do you want to accomodate "included" files (i.e. source files that
one /or more/ other sources "#include")? Do you count lines once in each
of these files, or do you count them for each time the source file is
included into another source file?

Once you've answered these questions, post your responses, and we'll have a
better understanding of what it is you want to count. From that, we'll be
able to properly provide suggestions on how to count your "lines of code".
