Ygor,

I tried your suggestion as follows:
a=1
b=2
c=3

Printf ‘ M = %s Ohms X = %s Ohms T = %s %%' $a $b $c

The above format worked fine but when a Command Substitution is used to set the Variables, I noticed that it does not give the right output. I did the following:

#value of lrs = 710
lrs=`cat lrs`
#value of hrs = 910
hrs=`cat hrs`
#value of tp = 3
tp=`cat tp`
printf ‘\n\nM = %s Ohms X = %s Ohms T = %s %%\n\n\n' $lrs $hrs $tp

The output is:
%hms T = 310

The desired output should be:
M = 710 Ohms X = 910 Ohms T = 3 %

NAME
optimise - output data file formats DESCRIPTION
This manual page describes the output formats of the files created by the Yagi-Uda project's optimise program. The input files required for optimise are plain ASCII which can be generated by input or first. or may be generated manually with a text editor, if care is used. The format required by optimise is described in input(5). Optimise's output files, which have the .bes extension are the same format as the input files and are again obviously described by input(5). Example of a .up file. The .up file list the improvements made by optimise to an antenna design. Starting from the original design, the file is appended each time a new better design is found. Here is an example, where the final line is the performance of the 4 element beam with the .dat file shown earlier. 1 7.57dBi, 16.93dB F/B, Z=(31.77-56.34j) Ohms, SWR=3.95, SL=16.95 dB 84 7.58dBi, 16.93dB F/B, Z=(31.78-56.32j) Ohms, SWR=3.95, SL=16.95 dB 623 7.58dBi, 16.93dB F/B, Z=(31.78-56.28j) Ohms, SWR=3.95, SL=16.95 dB 89345 9.74dBi, 103.06dB F/B, Z=(37.55 +1.61j) Ohms, SWR=1.33, SL=17.78 dB What is what in the .up file The first column is an integer specifying the iteration. The other columns, going from left to right are gain(dBi), FB, input impedance, VSWR and level of the most significant sidelobe, in dB down on the peak gain.
