In the TWOSAMPLESURVIVAL statement, the amount of required memory is roughly proportional to the product of the number of subintervals (specified by the NSUBINTERVAL= option) and the total time of the study (specified by the ACCRUALTIME= , FOLLOWUPTIME= , and TOTALTIME= options). If you run out of memory, then you can try either specifying a smaller number of subintervals, changing the time scale to a use a longer time unit (for example, years instead of months), or both.
