You can start McIDAS without logging on to the workstation as you did at the beginning of this lesson; however, some system and data files (e.g. grid files and string tables) you create or edit won't have your initials or project number saved with them. The LOGON command with the I (initialization) parameter modifies the session by:

• clearing the string table
• setting the image frame loop bounds from one through one-half the total number of frames
• setting the default dwell rate to nine units for the first frame and six units for the remaining frames
• setting the graphics line width to one pixel
• initializing the graphics color levels
• displaying a red, 31 by 31 pixel, cross hair cursor
• setting the enhancement table to 0 255 0 255 0 255 0 255
• clearing the buffer of remembered commands

1. Log on to the workstation. Type your initials and project number (Use 0 for the project number if you don't have one).

   Type: LOGON   initials   project#   I

   The message "LOGON to McIDAS-X completed" is displayed in the active text window.

   The LOGOFF command can be used if you are leaving your workstation and don't want others to use your initials and project number to access data.
