SPECX has a large array of flags and variables, which are changed using the various SET- commands,. At the same time, several spectra are stored in memory, in the data stack and storage registers. These two data sets together constitute the environment. A particular environment may take some time to develop for a particular application, and it would be a shame to lose it each time you exit the program, either willingly or inadvertently.
DUMP thus saves the current environment to the nominated file. Useful if you are using SPECX for analysis of several different data sets, and want to switch between two different setups; also useful if you do not have the automatic dumping facility turned on with SET-DUMP, and you want to protect yourself against losing everything in a crash (not that the program crashes any more!) Use RESTORE to recover an old environment from a dump file.
Examples:
>> dump<CR>
Dump file name? [SPECX_DUMP] specx.dmp<CR>
Common blocks dumped onto: specx.dmp
