how many cases

[Art Kendall]

PRINT has long been used in debugging. for example, ending a do if block when it reached ELSE.
Each DO IF block would put messages in the listing.
something like this untested example

do if condition1.
compute newvar=1.
else if condition2.
compute newvar=2.
else.
compute newvar=-1.
print /' problem in setting newvar' ' ID= ' ID 'Age = ' Age /.
end if.
do if gender eq 'male' and not missing(pregnancy#).
print //'ID = ' ID gender 'recorded as being pregnant' pregnancy# ' times/.
compute pregnancy#  = -1.
end if.

PRINT does not cause a data-pass to occur, and that is why EXE is needed.

I think of it as setting a flag.  Thus, if you have several PRINTs , they will be
run in the same reading of the file -- their results will be intermixed -- and
not in separate passes.
