How to define and import the values of string variables

masgari

I am working on sequential rietveld refinement of some PXRD data and I need to attach the name of CIF output CIF files to the Number of runs that has been defined as variable in inp. file. How can I do that?

For example, let's assume that I have a parameter defined as following:

prm !N = 10 ;

How can I make a CIF file with the name which follows the content of N parameter, i.e. in this case:
A CIF file with the name which is called "10.CIF".

Thanks,

Does the following do what you want:

Out_CIF_STR(cif_files\run_number_##Run_Number##.cif)

Thanks johnsoevans for your answer. I tried that but I couldn't make it. When I write the command you have written here, instead of the number, it writes the cif file with the name "Run_Number" instead of the Run_Number.
I think that somewhere I am doing wrong but I don't know where exactly.

This is the command that I have written:

Out_CIF_STR(CuBTT_NPD_Bare_10K##Run_Number##.cif)
and this is the name of the CIF file it has been produced:

"CuBTTr_NPD_Bare_10KRun_Number.cif"

It does not depend that I define the parameter or not! I tried to define the Run_Number like this:
prm !Run_Number 10
or
prm !Run_Number=10;

But this also doesn't work.

I should also mention I am using Topas 5.

Version 5 does not have Run_Number. Version 6 does.

However, the ## string concatenation sequence works in version 5 and the following should work:

macro Run_Number { 10 }

Out_CIF_STR(cif_files\run_number_##Run_Number##.cif)
