Well, the runs counter to the many sites that moved their applications
to PL/1, including State Farm (who trained 1,500 non-programmers to use
PL/1 in a 9 week course - those with musical ability, mathematical degrees,
or knowledge of two or more languages accounted for 90% of the folks who
were retained after that class!).  We benchmarked SAS, PL/1, and ASM
programs
in about 1973, and saw ASM's execution was faster than PL/1, which was only 
slightly faster than SAS, but the writing of the ASM program took 7 units of
time,
the PL/1 took 4 units of time, and SAS took 1 unit of time.

Barry,

My experience with PL/1 wasnt so good. In the 70's and 80's it was pretty
CPU intensive, i was on a 370/158 OS/VS2/HASP ...then later VSE on a 4381 ,
PL/1 probably is much better with the faster machines.
