Hammer & Screwdriver A few things to look at

(a) Much easier to read a script when you use codetags. After pasting in script text, highlight the script and select the '#' icon - which will maintain spacing of your script.

(b) You could store the variable names in a file, and then use the file to set all of the names. See the following

Code:
> cat sample2
INPUT_FUBX
INPUT_FSTV
INPUT_FGBR
INPUT_FJMT
INPUT_FWRP
INPUT_FQZN
INPUT_FPBT
INPUT_FMHQ
INPUT_FDGP
> cat sample2 | tr "\n" " "
INPUT_FUBX INPUT_FSTV INPUT_FGBR INPUT_FJMT INPUT_FWRP INPUT_FQZN INPUT_FPBT INPUT_FMHQ INPUT_FDGP  
> sample2x=$(cat sample2 | tr "\n" " ")
> echo $sample2x
INPUT_FUBX INPUT_FSTV INPUT_FGBR INPUT_FJMT INPUT_FWRP INPUT_FQZN INPUT_FPBT INPUT_FMHQ INPUT_FDGP

(c) Change the logic of your loop to read from the file [as you created in (b)]

Code:
while read zf
  do
  echo $zf  #showing the variable
  blah - blah
done <sample2
