DESCRIPTION

These notes summarize the modifications made for spec release 2.6, as finalized on June 6, 1988.

CHANGES

The User Manual, Reference Manual and Administrator's Guide are now relatively complete. The User Manual contains an introductory tutorial chapter on basic diffractometer operation.

The scan macros are substantially rewritten. Refer to the Reference Manual for a discussion of their present form.

The temperature control macros are substantially rewritten. Refer to the Reference Manual. In addition, thermistor conversions are now handled entirely within the macros.

The plot-results output is now generated in a macro named plot_res, that can be invoked separately and can be easily modified by the user.

The motor name unused is special. Motors with that name won't appear on any of the standard-macro generated output.

Bugs in the code for two CAMAC modules, the RTC018 clock and Joerger SMC motor controller, have been fixed.

Bugs in the code for the four-circle frozen modes have been fixed.

The geometry-specific standard macro file is now kept in spec.d/ rather than spec.d/conf/. The four-circle file is called /usr/lib/spec.d/four.mac.

The modulus operator (%) now correctly converts its operands to integers before operating.

New options for pl_anal() return the minimum and maximum values of x.

The names gpset, saveusr and savegeo replace _gpset, _saveusr and _savegeo.
