There is no real substitute for PROC SHEWHART.
You could use PROC SGPLOT to plot the data points and limits (you would have to calculate the limits prior to running PROC SGPLOT), but it would take a lot of programming to do all the testing that PROC SHEWHART does and then replicate this on the plot.

Thank you for your quick response. I had suspected as much, but hoped someone out there had found a simple solution.
