My son added a subversion repository to my site. I had added number functions, string functions, power, compares, stop, and end. I got run, goto, then, and else working and plunged on into on i goto a,b,c without committing run, goto, then, and else. The working version crashed. I couldn’t get it to compile no matter what I tried. I checked out the last revision that I had committed and added run, goto, then, and else. Needless to say, I committed them before moving on. Now I commit regularly.
