indexing program

[yesidgranadosv]

I have an indexing program but every time I use it generates an error :

"GOPTIONS ACCESSIBLE;
proc datasets library=DATA AML;
ERROR: El libref DATA AML no se ha asignado.
NOTE: Statements not processed because of errors noted above.
modify TBL BI CLIENTES;
INDEX CREATE NROIDENTIFICACION;
ERROR: There is no data set to modify.

 quit;"

I'd like to find a code that assigns me the bookcase before it's indexed.

I LEAVE MY INDEXATION CODE

proc datasets library=DATA_AML;
modify TBL_BI_CLIENTES;
INDEX CREATE NROIDENTIFICACION;
quit;

You need to have a library assigned before you can use it. Use the libname statement for this.

[yesidgranadosv]

it doesn't work for me, you can give me an example

[Kurt_Bremser]

libname mylib "path_to_library";

mylib is the reference you will use later, path_to_library is the fully qualified path to the directory as defined in the filesystem.

I have not been useful

Please post the whole log of the libname statement and the proc datasets. Copy/paste it into a window opened with the {i} button.
