Thank you Kit for pointing out that help text. What I'm looking for,
so far unsuccessfully, is guidelines on how to specify specific
formulas for cline_options for specific values of A and B.

The cline_options formulas I specified below were successful for only
the plot lines in which A==1 and B==1, or
A==0 & B==0.

However, but the other plot lines where
A==0 & B==1, or
A==1 & B==0.
remained a solid line in spite of my specification:

sts graph if stage==5, by(A B) lpattern(-) xtitle("Survival time in ///
months") l2title("Percent surviving") xmtick(0(10)150) ///
lpattern("l" if A==1 & B==1) ///
lpattern("--" if A==1 & B==0) ///
lpattern("--" if A==0 & B==1) ///
lpattern("--.#" if A==0 & B==0) ///


You need to think graphically, not logically in terms of what you're graphing. Your graph has four lines, and there are a number of graphics options that refer to the line number, not where that line came from. This notion is common to many aspects of Stata graphics.

. webuse drug2
(Patient Survival in Drug Trial)

. sts graph, cumhaz by(drug)

failure _d: died
analysis time _t: studytime

. sts graph, cumhaz by(drug) plot1opts(lpattern(shortdash_dot) color (cranberry))
> plot2opts(lpattern(dash) color(purple))

works for me.
