Re: Requesting new procs

Here's some syntax with a bunch of statistics including the "alpha if item 
deleted" option.  That option ("TOTAL") is actually represented in the 
/SUMMARY subcommand.

RELIABILITY
 /VARIABLES=a b c
 /SCALE('ALL VARIABLES')  ALL/MODEL=ALPHA
 /STATISTICS=DESCRIPTIVE SCALE HOTELLING CORR COV ANOVA COCHRAN TUKEY
 /SUMMARY=TOTAL MEANS VARIANCE COV CORR .
