What is the maximum length of LCALL instruction. I faced a problem while coding with LCALL.
 

But I cannot understand the problem... When I called a Label lying on the 474th line from 19th line... It is not working. Please help..
 

Without your code is impossible to help you... Lcall have 16bit space and must work!
At end of your subroutine have you ret statement? ...and enough stack RAM?
 

Sorry my code is little big. I am using AT89S52. Will it cause any problem with stack pointer?
