Q. What are the computer requirements to run Program CC?
A. A personal computer running Microsoft Windows 95 through 2000 is the minimum requirement.

Q. What is the difference between the Student and Professional Levels?
A. Program CC is available at two “Levels”- Student and Professional. Both Levels contain the same set of commands but certain restrictions are imposed at the Student Level. The Student Level allows access to all capabilities with limits on the memory for variables and the number of states. These limits should be adequate for most instructional applications in college courses. The Professional Level is intended for academic research and industrial use and no limits are imposed on memory size and number of states.

Q. Does Program CC, have programming capability?
A. Yes, Program CC, Version 5 has programming capability beyond the Version 4 “macro”. You can write your own functions in any text editor or directly in Program CC. The function files that you write, which should have the extension “mac”, will be executed like any other commands in Program CC.

Q. How does Program CC, Version 5 differ from Version 4?
A. Version 5 is a Windows program whereas Version 4 was a DOS program. Each of the various Version 4 packages had a different set of commands, whereas the two levels of Version 5.0 have the same set of commands. However, certain restrictions are imposed on the capacity of the Version 5 Student Level. A few functions in Program CC, Version 4 are not currently implemented in Version 5.0 (i.e., the kranc operator and H-infinity optimal control.) Please refer to the Command List for the commands available in Version 5.

Q. Are Program CC, Version 4 macros compatible with Program CC Version, 5.0 ?
A. No, since the Program CC, Version 5 programming capability has been improved from the old Version 4 “macro” capability, Version 3 and 4 macros must be revised to run in Version 5. Some of the commands in Version 4 are not compatible with Version 5. The Program CC, Version 5 commands are summarized in the Command List.
