I have seen use of 'CBL DYNAM' before Identification Division' an all the programs in our current system.
I guess this is to override the Compiler Option DYNAM/NO DYNAM. i.e. even if the compiler option is given as NO DYNAM as CBL DYNAM is specified all the called modules in the program will be linked dynamically to this module.
Please let me know if my assumption is correct. If not let me know what is the significance of this?
