No response when processing the thermal-scattering endf of H(H2O) with moder #299

I'm producing the WIMSD format 69-group cross sections of Hydrogen with NJOY. However, the program seems no response when processing the thermal-scattering endf of H(H2O) with moder.

Input: H_H2Os.nji.txt Screen output: H_H2Os.njo.txt Neutron reactions of Hydrogen: tape20.txt Thermal scattering of Hydrogen(in Water): tape30.txt

The mat number of Hydrogen thermal scattering in water is 1. Other mat numbers of thermal scattering are greater than 1. I'm not sure if this is why the program not responding. I succeeded in producing the cross-section of Carbon (in graphite). I would appreciate it so much if you could fix this no-responding.

Change the tape id number on tape30.txt so that it does not match the h-h2o evaluation's matn. It's not an ENDF rule but does confuse NJOY. Skip Kahler

I changed the tape id number on tape30.txt and the corresponding matn in moder and thermr of NJOY input. It works and the WIMSD library is produced finally. I'm wondering if it is necessary to modify the module moder of NJOY to fix this. Thank you so much for your help. @kahlerac.
