arcgis desktop - How to calculate Field using part of filename in ModelBuilder?


I am new to ModelBuilder and have not been able to figure how to use part of the FC name: For example the first FC in my GDB containing around 100 files is "A1005_GPS_Residence", and I need to calculate the new field SID = "A1005".



I have seen some posts with python and manually using the Field Calculator.


I tried using one expression, shown in the screenshot, but I am not sure if I can combine field calculations with inline substitution or the like !%Name%![1:4].
