Victor,

I think there is no specific limit on variables, but at the real device there is a limit of somewhat < 100kB for a script. This seems to be true in the Sim too.
calandar.js is getting rather huge (92k) currently.

I would suggest to shorten the code by

1. removing stale code ( code between /* */)
2. deleting/shortening comments
3. shorten var statements to var I=somthing, j, k=anotherting, ....;
4. shorten var names

HTH
