Create the activities data set and identify separate calendars. This data identifies two calendars: the professor's (the value of _CAL_ is Prof.) and the student's (the value of _CAL_ is Student). The Succ1 variable identifies which activity cannot begin until the current one ends. For example Analyze Exp 1 cannot begin until Run Exp 1 is completed. The DAYS value of 0 for JOBNUM 3, 6, and 8 indicates that these jobs are milestones.
