  PCAC> SET COUNTERS/STACK_PCS LINE PRIMES %LINE 22

      This command causes PCA to count the executions of line 22
      of module PRIMES when data collection starts, and enables the
      collection of stack PC values. For all further SET COUNTERS
      requests, a default of /STACK_PCS will be established.

  PCAC> SET COUNTERS PROGRAM BY ROUTINE

      This command specifies that execution counters be placed at all
      routine entry points in the user program.
