Thank you very much for asking us about improvements to your proposed poll.  I have some comments and recommendations below.

	The first 3 go up by a multiple of 10; the 4th by a multiple of 10,000.  It would be better if you rewrote choice #4 as:
	100K LOC - 1M LOC
	1M LOC - 10M LOC
	10M LOC - 100M LOC
	100M LOC - 1G LOC

	Here are a few more application areas in which Fortran is used:
	Financial analysis.  Much of the financial analysis software in the major financial trading firms is written in Fortran.
	Algorithm development
	Manufacturing applications, e.g., Shop Floor Control, Communication with PLCs, Control of Automated Storage and Retrieval Systems (ASRS), Tracking Work-in-Process (WIP) through the Production Process, Warehousing, Manufacturing Simulation

> 7)You program using Fortran because
>     Fortan is the best language
>     Fortran is the only language you know
>     Fortran is the language used in your lab/corporation
>     You need specific Fortran libraries (e.g. BLAS, NAG Fortran Library)
>     You work on/with a legacy Fortran code
>     other

	Here are a few more reasons to use Fortran.  Many of these are not very much appreciated in the language selection decision, but they do have tremendous impact on results.
	Human (i.e., Programmer) Productivity, e.g., Function Points / Direct Labor Hour and similar measures.
	Ease of understanding
	Ease of use
	Easy learning curve
	High-powered syntax, in terms of how much you can accomplish in one or a few statements.  High-powered features include:  Whole-array operations, array section operations, user-defined operators, user-defined generics, etc.

	You may wish to spell out ifort in full, i.e., "Intel Fortran"


	Cross-language Development.
	You may wish to add Visual Basic.

	Operating System / Platform.
	You may wish to add a question about what operating system(s) the respondent is developing on / for.  I would ask about these, as well as any other significant platforms:
	Unixes.  Include 5 or 6 of the most widely used Unix variants.

	You may wish to add a question about what industry or kind of firm the respondent is working in.  The needs of for-profit commercial and industrial firms are often quite different from those in academia, non-profit organizations, or vendors of software products.
