Passing two files to awk
I want to pass the first file as input argument using -v then first get awk to go through mref then pert.txt

Code:
awk -v mref="reference.txt" -f ../../A-Scripts/convert-zv-zp.awk pert.txt

Code:
  BEGIN {
    Version = "V04"
    if ( !mref ) {
      usage(Version)
      print "ERROR: mref not specified"
      print ""
      exit 1
    }
    ARGV[ARGC++] = ARGV[ARGC-1]
    ARGV[1] = mref
    print ARGV[1]" "ARGV[2]
  }

# First time round, read the reference sound speed model
  FNR == NR {
    a[NR] = $2
    next
  }

# Calculate the fractional perturbation dc/c with respect to the reference
  {
    for (i = 2; i <= NF; ++i ) { $i = ($i - a[FNR]) / a[FNR] }
  }

# Print the depth and the corresponding dc/c
  { print }

hmm. Consider the FILENAME variable:
Code:
awk ' FILENAME=="mref" { process mref }
        FILENAME=="pert.txt" { process pert.txt } ' mref pert.txt
# more generally
f1="mref"
f2="pert.txt"
awk -v f1=$f1 -v f2=$f2 \
      ' FILENAME=="mref" { code to process mref }
        FILENAME=="pert.txt" { code to process pert.txt } '  $f1 $f2
