st: looping over observations

["emre ekinci" <eekinci2610@hotmail.com>]

I have 100 observations.

I want to execute some commands for each observation.here is the basic 
structure:

local i=0

while `i'<=100 {
local ++i

if ((husbage1>husbage2) | (husbage11 <husbage2)) {

stata commands
}

else {
stata commands
}

}

if the logical statment is true for the first observation, it executes all 
commands within the if statement for other observations as well, although 
the logical statement is false for some observations.
what is my mistake here? How can I write a loop that executes some bunch of 
commands (including if else statement)?

thank you.
