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 .

The procedure already exists in SPSS -- Reliability analysis, statistics,
Scale if Item deleted.
Could add the other statistics options as well if desired:
General procedure:
Take the matrix of included variables
Loop I = 1 to k
Delete the kth variable
Calculate and print alpha on the basis of the k-1 remaining variables
End Loop
Finish
