TPHREG with time-dependent (character) variables

Hi,
I have been using PROC TPHREG for some time, in analyses where my time-dependent variable is continuous (numerical data) things have worked fine.

BUT when I converted my time-dependent variable into quartiles (character data) my code stopped working. I made the necessary adjustments to the CLASS and ARRAY statements but I keep ending up with an output file full of decimal places (every observation somehow gets counted as censored)

Any ideas / assistance / useful resources would be greatly appreciated.

Cheers,
Elaina
