The Load command presents a directory box in which you may select a file to be loaded. The TAB key cycles among the file listing box, the directory listing box, and the entry box. The ARROW keys allow you to move up and down in the lists. The END key will take you to the end of a list, and the HOME key will take you to the top.
Only files with the extension specified in the Configuration setup will be displayed. To load a file, use the TAB and ARROW keys to highlight the desired file and press ENTER or click on the Load button. Pressing ESC or clicking on the ESC button will terminate the operation and return you to the main menu.
JIMSAIP will always check the selected file to see if it is in the FITS format regardless of the file extension. This gives you the flexibility to name your files as you need. For example, I like to name my files according to the time of the exposure using a yymmdd.ddddd format where the decimal day to 5 digits allows a resolution between images of about 1 second. To meet the DOS standard for naming files, the actual decimal point is implied and we use the 'dot' to separate the last three digits. Thus 96113012.456 would be an image taken in 1996, November and the 30.12345th day (02:57:46 on the 30th). This format allows sorting by time with earliest images first (or latest images first, if you desire). I keep image files in separate directories by date with no other files (except possibly .GSC files - see Help with GSC Files). I keep track of images with a regular database program that allows for searching on such criteria as object name, date, etc.).
After selecting the desired file, the program will present you with a button box which will permit you to select the buffer in which to load the file. Use the mouse to click on a choice, highlight the desired choice with the RIGHT and/or LEFT ARROW keys, or press one of the A, a, B, b, C, c keys.
The file will load and an advisory box will display data about the size of the image and any limitations such as a truncation due to insuffient memory to handle the size image contained in the file.
