Thanks to Kit for spotting the foolish error. If you used I as index,
you should use foo`I' within the loop.

Marjan asked

levelsof id, local(ID)

foreach I of local ID {
	hprescott myvar if id == `I', stub(foo)
}

egen foo = rowmax(foo*_*)


This code shouldn't run at all (beyond the first ID) because it will  
try to reuse the same variable names for each ID. You need to make the  
stubs vary by ID, like

stub(foo`i')

You will then get foo1.., foo2...,  etc. and you can use the rowmax  
trick on them.
