Automating check out /check in of each step?

[kinook]

I'm not sure if you are using 'group' and 'project' interchangeably, or if you actually have VBGs that each contain one VBP, but it sounds like you want a single step in your .bld file for each .VBP that might get built (so that you can selectively include only the ones you want to build at a certain time). You can use a single Subroutine Call step for each .VBP file, which passes the .VBP filename in a macro, then use that filename in the subroutine to checkout, build, and checkin. You will need to convert the filename to a VSS path for the checkin/out steps, and how that conversion is done depends on your directory and VSS structure. See the attached sample for one approach. Let me know if that helps or if I'm totally off track.
