Strings are often used as shorthand for typing commonly used commands, parts of commands, or non-executable text, and for initializing your workstation during logon. For example, if you often load satellite images centered around latitude 43:35:15 and longitude 98:25:40, you could assign the string name LL to the string 43:35:15 98:25:40. Then whenever you would normally enter the latitude and longitude coordinates, you could now use the string LL. For example, instead of typing:

IMGDISP dataset frame LATLON=43:35:15 98:25:40

IMGDISP dataset frame LATLON=#LL
