Dear Experts,

I am trying to read FICL in ZPL. Being new to ZPL I have simply tried this:

vec1(1) = 1
vec1(2) = 1
vec1(3)=1
vec1(4)=1
vec1(5)=0
vec1(6)=0.0366
vec1(7)=0
vec1(8)=0
vec1(9)=0
vec1(10)=0
vec1(11)=0
vec1(12)=0
vec1(13)=0
vec1(14)=0
vec1(15)=0
vec1(16)=0
vec1(17)=0
vec1(18)=0
vec1(19)=1

f=FICL(1)
PRINT "FICL=",f,

However, this returns always zero. I could not find any example or any more detailed explanation of ZPL FICL. Are there also several values returned by FICL, like SYSTEM and RECEIVER Efficiency? Can I set the specific configuration to return FICL?

Many thanks for some explanation or a hint to an example file.

Markus
