Could you enable a session variable to keep track of it?  If you have an 
"if" statement in mnop.php that calls the abcd.php page, then have that 
"if" statement also start a session and register a variable.  This way, if 
the variable you set is equal to a certain value, then you know that 
abcd.php was called from mnop.php.
