>In the Function, your CASE statements refer only to FIXED values "0001" and "0002" for UPSINO. UPSINO is the ID number for a piece of equipment. It could have a value of any string up to seven characters. So I can have a UPSINO that looks like "TC00001" "TC0002" , or even "LTC00045", "LTC00046", etc. And in the resulting cursor, there will be multiple lines for any one of these UPSINOs. So I want to alternate like "green bar" paper, but not by every other row, rather alternate when the UPSINO changes each time in the resulting grid.

OK, then here's a better one: add one integer field to your cursor and let's name it nColor. For each group you can assign it a RGB number of your choice. You can alternate two colors, or n colors - whatever you like.

Something like this:

n=0
dimension aColors[4]
aColors[1]=0xFFFFFF
aColors[2]=0x00FFFF
aColors[3]=0xE2E2E2
aColors[4]=0xFF7fFF

set order to upsino
locate
do while !eof()
   n=n+1
   if n>4
      n=1
   endif
   c=upsino
   replace nColor with aColors[n] while c=upsino
enddo

Then have

.dynamicbackcolor="ncolor"

...and there you are. No expressions to evaluate, no functions to call.
