# save¶

## Purpose¶

Saves matrices, strings, or procedures to a disk file.

## Format¶

save vflag path=path x, lpath=y;
save path=path x;
save x;


Parameters

vflag

(literal) version flag

 -v89 not supported -v92 supported on UNIX, Windows -v96 supported on all platforms. See also Foreign Language Interface, for details on the various versions. The default format can be specified in gauss.cfg by setting the dat_fmt_version configuration variable. If dat_fmt_version is not set, the default is v96.
path

(literal or ^string) a default path to use for this and subsequent save’s.

x

(literal) a symbol name, the name of the file the symbol will be saved in is the same as this with the proper extension added for the type of the symbol.

lpath

(literal or ^string) a local path and filename to be used for a particular symbol. This path will override the path previously set and the filename will override the name of the symbol being saved. The extension cannot be overridden.

y

(literal) the symbol to be saved to lpath

## Examples¶

spath = "/gauss";
save path = ^spath x,y,z;


Save x, y, and z using /gauss as the path. This path will be used for the next save if none is specified.

svp = "/gauss/data";


n and k will be saved using /gauss/data as the save path, quad will be saved in /gauss with the name quad1.fmt. On platforms that use the backslash as the path separator, the double backslash is required inside double quotes to produce a backslash because it is the escape character in quoted strings. It is not required when specifying literals.

save path=/procs;


Change save path to /procs.

save path = /miscdata;
save /data/mydata1 = x, y, hisdata = z;


In the above program:

x would be saved in /data/mydata1.fmt

y would be saved in /miscdata/y.fmt

z would be saved in /miscdata/hisdata.fmt

## Remarks¶

save can be used to save matrices, strings, procedures, and functions.

Procedures and functions must be compiled and resident in memory before they can be save’d.

The following extensions will be given to files that are save’d:

 matrix .fmt string .fst procedure .fcg function .fcg keyword .fcg

If the path= subcommand is used with save, the path string will be remembered until changed in a subsequent command. This path will be used whenever none is specified. The save path can be overridden in any particular save by specifying an explicit path and filename.
