b) The SUBROUTINES may alter variables which were declared as globals whilst functions, as explained in the previous posts, have no chance to do so.




I apologize for that lapsus. Of course we must consider and distinguish global variables and values passed as parameters to a function call. In KIX the latter are passed by value, hence as copies, and are destroyed on exit from the function.

I am working on a function calling another function, as calling a subroutine with GOSUB seems not to work from inside a function. The KIX manual states that GOSUB "label" can use also an expression. So my first approach was to pass the "label" as parameter to a function, like this:

Code:

doScheduledTask($startY, $startM, $startD, $nameOfSubOrFunction) ;call function

;Function declaration
FUNCTION doScheduledTask($startY, $startM, $startD, $nameOfSubOrFunction)
  ;depending on parameters $startY, $startM, $startD, etc. call sub or function

  GOSUB $nameOfSubOrFunction ;this is syntactically correct, but subs can not be called here

  $rc = $nameOfSubOrFunction ;so I modified all the code to use a function instead
ENDFUNCTION

;Function declaration
FUNCTION testTask()
  ? "we are in testTask() now"
ENDFUNCTION


In the latter form the desired function IS NOT CALLED, if I pass

Code:
doScheduledTask(2006,02,28, "testTask()")


Maybe it is not possible to call a function by the "label" being an expression like GOSUB $end, as illustrated in the KIX manual?

Thanks for your help, Rosario
