Hi Ben, I am getting "Unbalanced quote" error message when I use backslashes.We are using seq-2.1.16, it is probably too old. I will go ahead and use a workaround.
I just wanted to see if there is a quick and easy solution. Thanks, Hovanes. On 7/10/19 9:21 AM, Benjamin Franksen wrote:

But when I do it like this seq testSequencer, "D=TOF,P=" the result is that the SNL code does not recognize that I override the default value of macro P (which is not an empty string). Is there a way to pass an empty string as the macro value to the sequencer program directly from the "seq" command without manipulating non-empty strings in the code itself?It works if you say seq testSequencer, "D=TOF,P=\"\"" I think this is a bug in the parser for the macro definition string. Will try to fix. Cheers Ben
