dastepstatus() computes and prints out the values of F-to-enter or
F-to-remove, and their P-values at the current stage of stepwise
dependent variable selection.  You can use this information to select
the next variable to be entered (the one with the largest F-to-enter)
or remove (the one with the smallest F-to remove).  Component
'F_statistics' of variable _DASTEPSTATE is updated.

dastepstatus() returns as value an "invisible" copy of variable
_DASTEPSTATE.  This can be assigned but is not normally printed.
_DASTEPSTATE must have been previously initialized or updated by macros
dastepsetup(), daentervar() or daremovevar().

dastepstatus(silent:T) sets component 'F_statistics' of _DASTEPSTATE
and returns an invisible copy of _DASTEPSTATE but does not print the

You ordinarily don't need to use dastepstatus() directly since macros
daentervar(), daremovevar() and dastepstatus() all use dastepstatus() to
report F-statistic values and their P-values.  An exception is when you
want to enter or remove several variables at once and want to see a
report only at the end.  Suppose, for example, that you want to add
variables 2 and 4 together, but don't want to see a report after
variable 2 is entered.

  Cmd> daentervar(2,4,silent:T) # silently enter variables 2 and 4

  Cmd> dastepstatus() # print report
