end memstruct 
 
--352,  -- size 
 
? sizeof(SHFILEINFO) 
 
puts(1,"Enter ...") 
wait_key() 

This shows a size of 640, I expected a value of 352. If I comment everything out except szDisplayName or leaving szTypeName alone or commenting out the two arrays will show the correct value. Every other combination with array is wrong. Is there a mistake in my code?
