save — Write workspace to a file


\begin{rail} Save : 'save' '(' String ? ')' ; \end{rail}
The save function writes the contents of all the workspace variables to a file. The file is then closed. The file may be specified in the optional argument, with a default of SAVE. Functions are not saved. The variables can be read back from the file by using the read function (see Page [*]). $\Longrightarrow$ This is not an built-in function. This function is normally loaded on start-up from the save.r file in the standard rlib directory. Use of the -r option, incorrectly setting the RLAB_LIB_DIR environmental variable, or modifying save.r may make this function unavailable.
