The extension rpn is not allowed. I downloaded the defns.rpn file from http://www.aps.anl.gov/Accelerator_Syst ... ware.shtml

Hello Michael,

Thank you for your help. The files can be used as the test one.

Maybe it is ok about the rpn expression. When I change the lattice file like: ! % 1.46625 2 * sto Labc DL : DRIFT, L= 1.46625 2 * It works well. If the file is modified like: % 2.9325 sto Labc DL : DRIFT, L= "Labc" or like: % 2.9325 sto Labc DL : DRIFT, L= 2.9325 They all don't work. I doubt the val...

It seems that maybe there is some thing wrong about the percent sign % .
When I change the parameters setting like:
% 1.46625 2 * sto Labc
DL : DRIFT, L= 2.9325
it means parameters of elements are independent on the variable "Labc". But it still doesn't work.

Hello soliday, Thank you for your advice. I have tested this. There is a little bit difference: 1. (same with you) $ export RPN_DEFNS=/home/fenggy/.defns.rpn $ echo $RPN_DEFNS /home/fenggy/.defns.rpn $ ls -ltr /home/fenggy/.defns.rpn -rwxr-xr-x 1 fenggy Domain users 6622 Aug 22 /home/fenggy/.defns.r...

Hello Michael,

I have checked the file's location. They are shown in the figures bellow:

Hello, I wrote a lattice file which includes two lines like this: % 1.46625 2 * sto Labc DL : DRIFT, L="Labc" When I run the program, an error occurred with a warning: unable to open 1.46625 2 * sto Labc in mode r: No such file or directory ensure the RPN_DEFNS environment variable is set I checked ...
