Add SWMM Interface File Combine Utility to pyswmm

[bowguy]

I have to combine multiple SWMM inflow files into a combined fole. This can be done in the SWMM interface menu:

I have created a python script that does this for my use but since it looks like it is in the SWMM source code, it would be a great enhancement for pyswmm. I would be happy to take a crack at it but do not know where to start. Where is the SWMM source code for this? What kind of function should be added to pyswmm and where? Are there any examples?

My script is a bit hard coded for my use with no error checking, different time steps, etc. but it works

This is done in the Delphi or Pascal code in SWMM5. You can get the code for the UX from the EPA Download Site for SWMM5,

unit Ucombine;

{ Delphi Pascal unit that combines two interface files into }
{ a third file. The function CombineFiles is called from the }
{ the FileCombineForm dialog in unit Dcombine, passing in the }
{ names of the three files and returning True if the combine }
{ operation was performed successfully. }
