Hello,

I need to calculate the maximum value of the matrix from a file before 
plotting.
The following code works in Linux:

a=`echo "printf('%f',max(max(load('field.txt'))))" |octave -q`
set cbrange[0.8*a:a]

but in Windows gnuplot gives an error:

warning: system evaluation not supported by MS-Windows 32 bit

Is there the way to perform this calculation under Windows?
