st: Overriding a loop if 0 observations using tabstat

Dear Statalisters

I am having problems with a loop (1 below) that contains tabstat and
would appreciate any advice.

In the command below, there are 0 observations when `i'=0 and
`y'=male. I get a message saying no observations and the loop stops.

However, when I run the loop using the tab command (for example, 2
below), the loop does not terminate when there are 0 observations but
continues to cycle through all values.

How can I get the first command to override 0 observations?

Many thanks,




1.
foreach i in  0 1 2 3 4 5 {
foreach y in male singlet{
di "Var =`y' & GA=`i'"
tabstat bwtg if myga==`i' & intab1==1 & admit_ic==1 & bwtg<., stat(n
mean median) by(`y') col(stat) f(%9.0g) notot nosep

}

}

foreach i in 0 1 2 3 4 5 {
foreach y in male singlet{

di "Var =`y' & GA=`i'"
 tab `y' if myga==`i' & intab1==1 & admit_ic==1 & bwtg<.
}

}
