how to write data in an out file?

[cicilixiaoran]

Dear vesna,

Thank you for your help.

set outFileID [open filetoread.out "r"]
set b [read $outFileID]
close $outFileID
set a [lindex $b 1]
puts "a is $a"
Through the above command, I can get the second data "a" in the first lode step. That puts "a is $a" is putting out to the screen, if I want to write it in a new out file "strain.out", how to do it? And the next load step, I get the filetoread.out again, and get a second data "a" again from the filetoread.out, I want write it in this strain.out again. Finally, in the strain.out file, I can get all second data "a" from the filetoread.out generated from every load step. How to do it? Thank you.

Best regards
