Hi there,

The usual stupid “heckling” answers aside; I can help you with 1) no problem. I'm afraid I don't quite understand 2), however, I will use Pascal for part 1). Feel free to mail me on mystic.smeg@yahoo.co.uk if you need anything else.
---- part 1 in progress: please wait... ----

2)does pascal use this language--> αÏγÏαλξηγοθÏ?????? don't think so, so it would be a-z, A-Z, 0-9 and the special symbols.
1)the lex program in what language? I should presume pascal? write down the program, put it here and we will correct it for you.
