Thanks for the guidance.

In replacing the square brackets with round ones, would I also need to change the numeric value too to reflect the array format
Code:
normtemp          VAR WORD[4]                   ' used to store the desired temperature setting
  normtemp1       VAR normtemp[0]
  normtemp2       VAR normtemp[1]
  normtemp3       VAR normtemp[2]
  normtemp4       VAR normtemp[3]
So that normtemp[0] becomes normtemp(1)
