Hi,

if the variable is defined as external in the main
program , it will be allocated every time the program
runs and since EXTERNALS are global then it has to be
defined in all subprograms ( if needed ).


however if the main program calls another subprogram
that calls this routine , the variable comes to life
only when needed , and since it is  static ,its values
are preserved in between calls.


Thanks
