Better Way to Deal With Signed Int

[jecottrell]

Hello All,

I'm trying to store a value that can range from -1 to 65,535. It will arrive as a string and if the value is -1 then that is a flag otherwise it is a sequence number.

I can make a signed int32 to hold the value but it seems awfully wasteful. Is there a better way to skin the cat or am I making something of nothing? (btw, code space doesn't appear to be a problem yet.)

Thanks,

John

An elegant way would be to use a Structure containing an Int16 and a Short or boolean.

Ahhhh... thanks.

I had thought of using two variables, but thought that was kind of messy. Structures hadn't occured to me because I'm not that familiar with them... I guess it's time to make them my friend.

My general approach will be to check for a '-', and set that bit in the structure if necessary. Then parse the '-' character out of the string and then use the atol function to put the remainder of the srting in the int16 variable.

Sound about right.

Thanks,

John
