Rename all variables.

[annaba]

Hi, 

I'm trying to rename all my variables by cutting the first and the last letters.

I used this code :

data mine.petitVEST2;
set mine.petitTEST1;
run;
proc sql;
select cats(name ||'='|| substr(name,2,4)) into: rename_list separated by " "
from dictionary.columns
where libname="mine" and memname="petitVEST2";
quit;

proc datasets library = mine nolist;
modify petitVEST2;
rename &rename_list;
quit;

proc contents data = mine.petitVEST2;
run;

but I received this error message : 

79 proc datasets library = mine nolist;

80 modify petitVEST2;

WARNING: Apparent symbolic reference RENAME_LIST not resolved.

81 rename &rename_list.;

_

22

76

NOTE: Enter RUN; to continue or QUIT; to end the procedure.

ERROR 22-322: Expecting un nom.

ERROR 76-322: Syntax error, statement will be ignored.

Please help me!

Because your query will never match any variables. The LIBNAME and MEMNAME variables in that view are always in uppercase.

If you want to remove the first and last character you need to know the length.

catx('=',name,substr(name,2,length(name)-2))
