Android Question Arrays ?

[Colin Evans]

Hi, in my only previous programming language (M) one of the most useful features was globals, basically tree structured arrays

Name("00:30")="test"
Name("00:45")="test2"
Name("01:00")="test3"
Name("01:30")="Test4"

Not sure how to explain, but I want the array key to hold a string rather than a numeric value, then when I want get the data side i can simply say X = Name("00:45") and X would equal 'test2' does that make sense, can it be done, basically I wish to read in some temporary data into an array list and then compare the value of a select variable against the one held in the temporary array list, so if some one selects a specific time I can get the value held in the, in this example Name array list, sorry to be so vague

@Colin Evans have you looked at 'Map'...

I have now, thank you but is there any way of making the values available to any module, I can put the data in RatesChk.Put(tim0Chk, invChk) but I can't seem to access it from my other module where I need to extract invChk with 'InVData = RatesChk.Get(tim0(i))'

Thanks found a way round with File.WriteMap and File.ReadMap

Be careful: The same key overrides the previous one. So create single maps and add them to a list.

This way:

only if they must be permanently saved, i.e. available at each start of the app.
Otherwise, simply declare your Maps as Public in the Starter service or in a code module.
