Bob,

Since p values take the range 0-1, you only have small subset to consider
for creating your own format. Would something like this work? Adjust when
you have to conside another w.d.

proc format ;
  value mypval 0.0001 - 1 = [pvalue8.4]
               0 - <1e-4 = "<0.0001" ;
run ;

data _null_ ;
  input x ;
  put x = : mypval. ;
cards ;
1
0.01
0.001
0.0001
0.000001
0.00001
run ;
