flag.print	When TRUE, the whole contents of the table is dumped out
flag.class	When TRUE (and if flag.stats=TRUE and a variable is specified), the statistics of the selected variables are produced by (non empty) integer classes.

db.print(Z_data.db,flag.stats=TRUE,name="z1") # Stats on 'z1'

# Add the statistics by integer classes
db.print(Z_data.db,flag.class=TRUE,name="z2")

# Print the contents of the Db
db.print(Z_data.db,flag.print=TRUE)
# Note that only the first 'Ntrow" rows 'Mtcol" columns are printed
# Use environ.print() to check these values and
# use constant.define() to modify them
