Thanks Jeff,
I already used the q w2xy and I don't see any error.
Here is the rest of the script
file ="lightning_from00z29April.004.txt"
colors="1 2 3 4 5 6 7 8 9 10 11 12 13"
ccount=0
rc=1
while (rc != 2)
data=read(file)
rc=sublin(data,1)
if (rc != 2)
line=sublin(data,2)
chk=substr(line,1,10)
if (chk != "----------")
lat=subwrd(line,1)
lon=subwrd(line,2)
flag=subwrd(line,3)
color=subwrd(line,4)
"q w2xy "lon " " lat
xloc=subwrd(result,3)
yloc=subwrd(result,6)
name=subwrd(ccount,1)
"set line "color" 1 5"
"set lat -20 20"
"set lon -40 25"
"draw mark "flag " "xloc " "yloc " 0.1"
* "draw mark 1 " xloc " "yloc " 0.06"
else
ccount=ccount+1
endif
endif
endwhile
'set string 1 tc 1'
'set strsiz .30'
