LogiView

Command 'exit'

     

This command cancels the execution of decision table(s) / procedure(s) and returns program control to the DataView event handler.

If LogiView is called as a mask or field userexit ('lgv_pre_fld', 'lgv_post_fld', 'lgv_pre_mas' ...), the termination is evaluated with an 'exit' error message.
 

Syntax:

  exit()
 

I/O parameters:

-  
-  
 

Return value:

 
-  
 

Example:

  Declaration of Variables
 

Call of a "post field trigger" decision table ('lgv_post_fld' userexit) for verification of current input:

T Ln Con/Act R 01 ELSE
B 10 sel_value(act_fld) <= DOCU_INT_1  
    -------------------------- ---- ----
A 20 put("Size of input too small!") yes no
A 30 exit() yes no
 
  Result:
  The user cannot move on to the next field until a value is entered that is larger than the one defined in the DOCU_INT_1 numerical variable.
Please note that the Else clause is required (even if it does not contain any actions). Otherwise the field can never be left since a matching rule has to be found - i.e. the Else clause.
