Your programmers will be up and running with Spectrum Writer in no time. And yet it still provides dozens of the same powerful string manipulation, date manipulation and formatting functions found in those vastly more expensive products. Best of all, it is written entirely in fast, efficient Assembler language to be easy on your CPU.
Use Spectrum Writer to: - create brand-new custom reports in just minutes

- e-mail attachments
- Oracle databases
- Unix Web servers
- any other mainframe, mini, or PC application that requires a custom file format
Suggested FOCUS Replacement Strategy:
Spectrum Writer is not a "plug-compatible" equivalent of FOCUS: Spectrum Writer uses its own easy 4GL language. So you will want to factor in to your cost savings calculations the cost of migrating your existing jobs.
We suggest the following staged approach toward achieving your big annual savings with Spectrum Writer.
1. Download a free 30-day trial of Spectrum Writer. See for yourself how powerful and easy Spectrum Writer is. During your trial, we will be happy to help you convert some existing FOCUS reports to run with Spectrum Writer. You can then judge whether Spectrum Writer is a practical replacement option for your shop.
2. License Spectrum Writer for your shop, either permanently or just for one year to start.
3. Start right away to use Spectrum Writer for all new ad-hoc report requests, to begin lessening your dependence on FOCUS.
4. Over time, convert existing FOCUS applications to Spectrum Writer (or to COBOL etc., if more appropriate.)
5. Finally, drop FOCUS and enjoy your savings year after year! You'll quickly recoup your modest investment in Spectrum Writer.
