| Subject: | VAL keyword in calcout records |

Hi,I just learned that the recently introduced VAL keyword does not (quoting the Record Reference Manual) return "the current contents of the VAL field" but rather "the current contents of this expression's result".
Which means, that inside a calcout record's OCAL expression, VAL refers to OVAL, not VAL. Which means you can not use VAL inside OCAL to refer to the result of the CALC expression, but have to repeat the CALC expression inside OCAL to get the same value.
Which (in my case) makes the OCAL expression more than 40 characters long, which doesn't work.
Should we change the behaviour or the documentation? Ralph
