Return Value
None.
Description
Multiple arrays can be freed at one time.
Use this command to free array variables that are used only temporarily. Doing so will allow the most
effective use of memory space.
An array that has been freed can be defined again under the same name.
When an array is re-defined with the same name without freeing it, the array defined the most recently
will be valid. In this case, the array defined before will be freed and re-defined.
Example
Free a defined array.
Dim ARRAY1&(100),ARRAY2&(200),ARRAY3&(300)
:
Erase ARRAY1&(),ARRAY2&(),ARRAY3&()
Gets the Error occurrence commands during exception handling.
Errcmnd$
Parameters
None.
Return Value
Returns the value of the character string.
The content of the value is the command character string generated by the error.
Description
Gets the error command character string when a Macro Error is generated.
The command character string gotten will be an alphabetic upper case character string.
When no error has occurred a null string ("") is returned.
In cases where an error occurs somewhere other than in command processing (i.e. an error such as that
caused by dividing by zero in calculation), a null string ("") is returned.
This is used between the catch~end try of try ~ catch ~ end try.
Example
Writing data to a file.
