Parsing commands and parameters

[richard]

so a command is *99 or *9 or *09 [where 9 == a numeric digit]
and a parameter is 9 up to 999999

how do you signal that the command has been input and the parameter begins

i would be tempted to use the # as enter

so cmd 33 p2010 would be
*33#2100#
you will need to establish a method to cope with numbers bigger than a word

you need a method first then code it

For a more compact and maybe easier to code the command and data be at defined length.

So command 9 would be 09 and data 9 (this is extreme but for the sake of discussion) would be 00009.

So there is no need for extra termination character.

Also I think word or long variable may not be helpful here. Better an array, since the data are distinct in meaning so a 433925 would mean 433,925MHz in reality as an absolute value.

The beeps would help user to step with confidence entering the commands and data.

I think stuffing an array and then select case is the way to do it.
