Answer:How to extract ASCII string data file header and use as plottitle

[Lev Tarasoff <lev@xxxxxxxxxxxxxxxxxxxxxxxxxx>]

Thanks to Mick and Steve, here is one way to extract ASCII string data
file headers and incorporate them into plot titles. (Shown here is for
incorporation into a shell script for quick plots. If one was interested
in accessing file headers within an interactive ferret session, one
could invoke the following with a "spawn" command). Replace
"myplotscript.jnl" with your own  plotting script and set up the
following shell script: ("echo ... >>tmpB.jnl" should be one line)


------------------shellscript run.plotwfileheader----------------------
#!/bin/csh
#extracts file header string and appends a label to top of ferret plot
cat myplotscript.jnl >! tmpB.jnl
echo `head -1 idat121.$1 | awk '{print "ppl %label/nouser 4 6. 0 0 0.2
@P7"$0}' >> tmpB.jnl
ferret -batch HD{$1}BW.ps << EOF >& out.tt
go tmpB $1
quit
EOF
rm -f tmpB.jnl

------------------end of shellscript run.plotwfileheader------------------

cheers
