Re: a new problem with Ref()

I'm not a function builder [yet] but a couple of thoughts occurred to me ...

When you say it quits working do you mean XNINE does not get a value, the 
system crashes... ???

Would it be possible to put XNINE first in your program? Just for testing. 
Then would XEIGHT fail instead?

I assume that MXX, -8 is telling the system to get data from 8 periods ago. 
If so would it be possible that MMX, -9 [9 days ago] the data is incorrect 
and provides an inappropriate value which creates a problem in a calculation?

Don't know if my thoughts are useful but I thought I would pass 'em on to see 
if they help out.

BTW Are you still looking at options? How's that going?

 I have a variable called MXX.  I am manipulating it in a simplistic manner
 and the first 8 worked great.  When I get to the ninth iteration, it quits
 working.
 
 XEIGHT:=  ( MXX - Ref( MXX , -8 ) ) / 8;   This one works correctly
 XNINE:= ( MXX - Ref( MXX , -9 ) ) / 9;       This one doesn't work!
 
 Actually, numbers one through eight work fine.  Nine and ten don't work and
 I haven't finished checking eleven through twenty yet.  I assume there's
 something in the manual I missed, so any help would be appreciated.
 
 Thanks,
