Questions: 1) As no malloc() was used to allocate memory for out, str1 and str2 in your strmerg() function. Is it because they are all declared const char* ?
Look closer, they're not all const char *.
It's nothing to do with malloc.
The two which are 'const char *' are set that way because I don't need to write to their contents.
The one which isn't 'const char *' is because I need to write to its contents.
I could have made them all plain 'char *' and it would have still worked. The 'const' is a reminder to me, the programmer, of which arguments I should be writing to and which I shouldn't. It's also a safety mechanism, so if I try to cram unwritable things into it, the compiler will complain.

2) In main() char out[4096] was used to hold the merged string, in practice, string 1 and string 2 can be as large as mega-bases. I thought dynamic allocation of the memory for out using a pointer would be better. It seems there is no such thing in C to dynamically allocate space for the merged string based on the two inputs (???).
...and having said so, you go ahead and do the "impossible" in the same breath
I avoided malloc because pointers still confuse you. I just thought it was more straightforward to do it that way.

Can I ask if if there is anything inappropriate with my modification on main() function?[/COLOR]
Actually that looks fine. It allocates more memory than it needs to so isn't ideal, but will do what you want it to do, and won't crash.
Here's what I would do:

Hello all,
I have a question about what you think the best practice is to determine what region you are running on when you have a system setup with a DEV/TEST, QA, and PROD regions running the same scripts in all.
So, when you run in DEV, you have a different directory structure, and you... (4 Replies)

chr3 200 1500 gene3
if it overlaps with a feature in this file2:
