In eating my own dog food I have revised, corrected, improved and fixed the code I posted last week. The biggest changes are related to ensuring that all that cached data does not just accumulate and never gets cleared away.
Values set using the “GM_setValue” function are saved in the Firefox preferences back end and [...]

See Greasemonkey) has two persistent data function’s, GM_setValue and GM_getValue, which let you set and get values. See Mark Pilgrams excellent Dive Into Greasemonkey : Storing and retrieving persistent data for more details. (even better, go to GreaseSpot and it’s api [...]

In mathematics, the intersection (denoted as ∩) of two sets A and B is the set that contains all elements of A that also belong to B.
I needed the javascript array equivalent, so that given an array A = ["a","b","c", "d"] and B = ["b", "d", "e"], getIntersect(A, B) = ["b", "d"]

I had hoped to use the “@ThisName” to get the suffix of the field name “Comment_1″ and hide it if the Field “Status_1″ is “Pending” by doing this :
1234Suffix := @Right(@ThisName; "_");
EmpListFieldName := "Status_" + Suffix;
Status_value := @GetField(EmpListFieldName);
@If( Status_value = "Pending";@Return(@True);@Return(@False));
but it didn’t work
