store a phone number

if i want to store a phone number in a variable how do i do this? is it a long and if so by looking at the help on this site it uses commas to separate the numbers

how do i stop this? or am i up the wrong tree?

long emer6 = ('09995953758'); is this correct ?? this information will be on an SD card eventually and loaded from there

If you store it as any type of number you will lose any leading zeros. So you need to store it as a character array.

ok thanks i will try that

Better stored as BCD digits - lower memory requirements.

AWOL: Better stored as BCD digits - lower memory requirements.

what's that i've never heard of that? do you have any samples of this method ?
