Hi mfrancis!

Your use of the jump feature has an extra - character. Right now, it looks like


24<-999


Remove all of the dashes any time you have the jump command so that it instead looks like


24<999


Then try running that input file a few times to see if all of the data records. This test version of the input file should also not use any randomization so that you do not have to contend with that as a confounding variable.
