LogiView

Function 'default_get'

     

This function checks if a DataView default with the specified name (for the user) is set. If so, the function returns a "TRUE" result and assigns the default value to the corresponding variable.

If the value cannot be converted to the variable type, LogiView aborts the execution and displays a corresponding error message. If no default is set for the specified variable, the function returns "FALSE". In this case the variable is not changed.

 

Syntax:

  {LOG_VAR}= default_get ({STR_EXPR}, {VAR})
 

I/O parameters:

{STR_EXPR} Name of default setting (in capital letters).
{VAR} Variable to be defined with the default value
 

Return value:

 
{LOG_VAR}
TRUE Default is set
False Default could not be set
