Syntax

rc=LNAMEGET(path-string,type,<name-string1<,name-string2><,options>>);

rc

contains the return code for the operation:

0	successful
>0	not successful

Type: Numeric

path-string

is the string generated by LNAMEMK.

Type: Character

type

is the type of the path. See LNAMEMK for more information. If no other arguments are specified, the function returns only the type.

Type: Numeric

name-string

is the name-string provided in LNAMEMK. Specify enough name-string arguments for the type. See LNAMEMK for more information.

Type: Character

options

are any options used with LNAMEMK.

Type: Character

Details

Path strings that are created by LNAMEMK are not readable, and their internal format may change from release to release. The only way to decode a path string is to use LNAMEGET.

You may find it useful to encode an image filename with LNAMEMK and to store that path string in a SAS data set. Then, later retrieve the path string and use LNAMEGET to find the arguments that were originally specified in LNAMEMK.

If you use the type, name-string, and options arguments, they are filled with the corresponding arguments specified in LNAMEMK (such as the libref/member name, physical pathname, and so on). The number of optional arguments that you specify must match the number specified in LNAMEMK.

Examples

Encode and decode a pathname. Store the type of path in TYPE, and store the pathname in IMGFILE.
```
imgpath=lnamemk(1,filename);
rc=lnameget(imgpath,type,imgfile);
```
Encode and decode the location of an image file. Store the directory that contains the image file in DIR, and store the filename in IMGFILE.
```
imgpath=lnamemk(2,dirname,filename);
rc=lnameget(imgpath,type,dir,imgfile);
```
