HOW TO
Determine the execution time for one or more ArcInfo Workstation commands in an AML
Summary
The AML function [show &PT {TIME | CPU | DIO | ALL}] allows you to determine how many seconds one or more sequential Workstation ArcInfo commands take to perform.
Procedure
Enter two performance timers [show &pt time] function lines into an AML script. The first [show &pt time] function initializes the performance timer. It must precede the line or lines you want to time. The second [show &pt time] returns how many seconds have passed while the commands between the the first and second [show &pt time] line where executed. The second [show &pt time] line must be placed immediately after the last command being evaluated.If you run this AML, you will see approximately 15 seconds pass on your wrist watch between when the "Waiting:" prompts appear on the screen and the performance time is listed for both AML PAUSE commands.

/* The second [show &pt time] returns seconds since the previous [show &pt].
/* Since the two &pause directive pause execution for a total of 15 seconds,
