Can't do math in fieldlen()

[Keith F Weatherhead]

Greetings,

I just ran into a new problem today using fp 5.0.13 on SCO Unix, 
whereby if you try to do the following it doesn't work...

::Declare Pntr1(8,.0), Value1(8,.0):
::Pntr1="90":
::Value1=fieldlen(lookup_name,Pntr1+"3"):

Value1 get assignned as zero, even when the field exists and is 
defined, however...


Now, by adding...
::' to the above example where the declare is:
::declare Pntr2(8,.0):

::' after the Pntr1 assignment:
::Pntr2=Pntr1+"3":

::' replace the line with fieldlen() with...:
Value1=fieldlen(lookup_name,Pntr2):

Value1 now has the correct field length value in it.
Odd?  There aren't too many places in the language where you cannot 
do math in the position of where you want that value placed, but 
fieldlen() appears to be one of those places...

Regards,
Keith
