The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

Sharing Variables
 
You can share variables among parts of a module without making the variables
global by using the SHARED statement. For example, to share TabStops
without making it a global variable, you would add SHARED statements to the
particular procedures you want to share the variable:
 
  DIM TabStops(MAXLINE)
  .
  .
  .
  SUB SetTabPos STATIC
  SHARED TabStops()
  .
  .
  .
  END SUB
  FUNCTION ThisIsATab(LastColumn AS INTEGER) STATIC
  SHARED TabStops()
  .
  .
  .
  END FUNCTION
 
The SHARED statements indicate that the name TabStops in both procedures
refers to the same variable defined at the module level.
