in varnw1 (the values shown in the current version of the 1st message in this thread) and we put the sample data from that message in file1, the results my script puts in file2 is:
Code:
Data 1
Value One 54.24425 +29.99999
Value Two 35.24535 -10.00000
Other values in the list 25.53231 -59.71304

Data 2
Value One 24.24225 -20.00000
Value Two 35.24535 +10.00000
Other values of new 28.350132 -26.785328

which matches what you said you wanted in that message.
Don, you are right here again,the script meet with the requirment of the first message in this thread.

If you decided to switch the order of the operands in the subtraction in your calculations and didn't bother telling us that you had done so, it is not a bug in the script! If want to change your requirements again, have the courage to say that you want me to change the script again to meet your new requirements. Don't tell me there is a bug in my script when it behaves exactly as you said it should behave. Smilie
I haved noted this in the last run of the script, I appreciate your help so do not be mad.

Tcl_AllowExceptions(3)					      Tcl Library Procedures					    Tcl_AllowExceptions(3)

__________________________________________________________________________________________________________________________________________________

NAME
Tcl_AllowExceptions - allow all exceptions in next script evaluation SYNOPSIS
#include <tcl.h> Tcl_AllowExceptions(interp) ARGUMENTS
Tcl_Interp *interp (in) Interpreter in which script will be evaluated. _________________________________________________________________ DESCRIPTION
If a script is evaluated at top-level (i.e. no other scripts are pending evaluation when the script is invoked), and if the script termi- nates with a completion code other than TCL_OK, TCL_ERROR or TCL_RETURN, then Tcl normally converts this into a TCL_ERROR return with an appropriate message. The particular script evaluation procedures of Tcl that act in the manner are Tcl_EvalObjEx, Tcl_EvalObjv, Tcl_Eval, Tcl_EvalEx, Tcl_GlobalEval, Tcl_GlobalEvalObj, Tcl_VarEval and Tcl_VarEvalVA. However, if Tcl_AllowExceptions is invoked immediately before calling one of those a procedures, then arbitrary completion codes are per- mitted from the script, and they are returned without modification. This is useful in cases where the caller can deal with exceptions such as TCL_BREAK or TCL_CONTINUE in a meaningful way. KEYWORDS
continue, break, exception, interpreter Tcl 7.4 Tcl_AllowExceptions(3)
