Concat Variable names

[Aman4SAS]

i have a data set like

data test;

input x y z;

..........

run;

i want a macro variable like x|y|z (concatenating the variable names)

is it possible in sas by proc sql or anyhow?

Hello,

with proc sql:

data test;
x=1;y=2;z=3;
run;

proc sql noprint;
select name into :allvars separated by '|' from sashelp.vcolumn
where libname='WORK' and memname='TEST';
quit;

Do you want to concatenate the values of the variables into a new field?  Or create a SAS macro variable with the variable names?

If the latter, try something like this:

proc sql noprint;
select name into:MyVars separated by ' '
  from sashelp.vcolumn
  where libname="WORK" and memname="TEST";
quit;

%put &myvars;
 

If the former, then you can use one of the CAT functions (such as CATX) to create a new value in your DATA step:

newVal = CATX(' ',x,y,z);

That's not a macro var though.  If you need the macro variable you'll need to decide which particular record you want to represent, calculate the value, and you can use CALL SYMPUT to stuff it into a macro variable for use later in your program.
