Right - a couple of easy peasy questions for you ada gurus out there:

Im rewriting an old program of mine to be used at university. Every Unix
machine has a user id number which can be easily found to which i want to
write a program called `xtwhere` which tells you which lab that computer
with that id number is located.

(1) I want people to be able to type:

xtwhere <machine_id>

to which it runs the program `xtwhere`. How can i find out what the
<machine_id> written was? - an example of this might be

xtwhere xt027

(2) I need to split this <machine_id> into two parts - a text bit (the
`xt`) and the number bit (the '027') - If the answer to (1) returns a
string how can i convert a string into a number?

Please could you mail any suggestions/answers to me as i dont regulary use
this newsgroup.

Regards

Rich.

One can convert a string into a number by using Ada 95's "'value"
attribute.

  i := integer'value("123");
