The GANTT Procedure |
Naturally, there needs to be a sufficient amount of core memory available in order to invoke and initialize the SAS System as well as to meet the memory requirements of the specific mode in which you invoke the procedure. For example, more memory is required when using high-resolution graphics than when using line-printer mode since the graphics sublibrary has to be loaded. As far as possible, the procedure attempts to store all the data in core memory. However, if there is insufficient core memory available for the entire project, the GANTT procedure resorts to the use of Utility data sets and swaps between core memory and Utility data sets as necessary.
The data storage requirement for the GANTT procedure is proportional to the number of activities in the project, and it depends on the number of schedule variables, the number of ID variables, and whether the Logic and Labeling options have been specified or not.
