Array: Return name of variable at specific position in the array

[juju_p]

Hello,

I would like to do something with SAS but I am not sure how to go about it.

I am looping through an array of 3 elements and whenever I have a match, I would like to print the name of the element itself and not the content of the element.

Is this possible with SAS?

Thanks a lot!

Array CT (3) CT1 CT2 CT3;

DO i=1 to 3;
IF CT(i)  = 1 THEN DO;
IF CT = '' THEN CT = CTi;
ELSE IF CT^= '' THEN CT= strip(CT) || '/' || strip(CTi);
END;
END;

The vname function can do this.
