Hi Igor,

This kind of question is best posed on the comp.lang.tcl newsgroup. But studying the source code I conclude that the code as you posted it would never reach the [puts] statement: step keeps a value of 0.1 and is never changed within the while loop. So the question is: is this really the code that is going wrong in the sense that you imply?

As a matter of style: always brace your expressions: set tmp_val_PHI2 [expr $tmp_val_PHI2 + $step] ==> set tmp_val_PHI2 [expr {$tmp_val_PHI2 + $step}]

(You could end up with the error message if the closing brace is placed in the wrong place)

Regards,

Arjen

Hello there,
This is a small part of app written in lisp. And there is something wrong

proc make_lst_of_val_PHI2 {tmp_val_PHI2 step
                             tmp_lst_of_val_PHI2} {
set tmp_val_PHI2 0
set step 0.1
set tmp_lst_of_val_PHI2 0
while {$step < 6.28} {
set tmp_val_PHI2 [expr $tmp_val_PHI2 + $step]
lappend tmp_lst_of_val_PHI2 $tmp_val_PHI2
}
put $tmp_lst_of_val_PHI2
}

output no such variable tmp_lst_of_val_PHI2.
