Creating it how - from a shell, in a program? With system or stdio calls?

The mode of a newly created file is set (and modified by the umask)
in the low-level creat(2) or open(2) system call. Most applications -
including anything using the C library's fopen(3) call - don't set the
execute bits at the time the file is created. So your umask setting
allows the execute bits to be set at file creation if the app requests
it... but the app still has to request it.
