MarvinSketch Example 3.2
To speed up the downloading, you can specify the molfile inline instead of as a URL. This requires the browser to perform fewer http GET requests.

You can further decrease the download time by compressing the molfile:
msketch_param("mol", "3,7-Dihydro-1,3,7-trimethyl-1H-purine-2,6-dione\n"+
" Marvin 07099920012D\n\n 14 15 0 0 0 0 0 0 0 0999 V2000\n"+

You can create this type of JavaScript string from an existing molecule using the "Edit
Source " window of MarvinSketch or MarvinView
(Edit -> Source). Choose Format ->
Compressed mol, then Format -> Convert to Java String.
If you decide not to use the utility functions in marvin.js, then the corresponding MarvinSketch/AWT applet tag is the following:

Don't forget to end each line with a backslash.
The reason for ending the lines with this special character is that web browsers
filter out the real linebreaks from such multiline strings.
In examples 3.1-3.2, the applet loaded the molecule at startup. However, in some cases it is necessary to load a molecule at runtime.
