The first version of this section appeared as the `SPECX Cookbook' and was written by Thomas Walker. He moved on to greater things, but still accepts accolades and greenbacks at walker@stsci.edu.

The VMS version of SPECX requires the number of spectra expected in addition; Unix allows the files to be expanded indefinitely.

SPECX prompts you for an `EOF' (end-of-file); what the Unix-types don't tell you is that this is a Control-d; it is Control-z under VMS.

SPECX uses an HP calculator-like stack; the x-register is on the top, and is the one which is always plotted.

There is the special case when both subsystems of the DAS are used to provide ultra-wideband coverage with C2 - these are handled as two separate spectra each of 8 subbands (see Section .

By the way, in case I didn't mention it before any characters following a `!' on a command line are taken to be comments. I often use comment lines to `store' command lines I might need some other time.
