hi,

how about the following code?

===================================

set fp [open "lines.dat" r]
set dat1 ""
set dat2 ""
while { ![eof $fp] } {
     set dat2 $dat1
     set dat1 [gets $fp]
     if { ("$dat1" != "") && ("$dat2" != "") } {
       draw line $dat1 $dat2
     }
}
unset dat1
unset dat2
close $fp
unset fp

====================================

axel.
