Advanced features: using regular expressions.

           Together with the mlneeded fields you can use regular expressions
           to tell TECForm under what conditions it shoul accept certain
           fields. A field specification can be accompanied by a regular
           expression, to tell what form a field sould have if it is filled in.
           If a field is filled in it has to match the specified regular expression
           in order for the input to be accepted, if the field isn't filled
           in it is left to the mlneeded meganism to determine if the form
           will be accepted.
           A reggular expression is added to the name of a field in the
           following way:
           Lets say you have a field that is called e-mail, and it has to be a
           string that could be a valid e-mail adres, you could do it like this:

           <INPUT TYPE="TEXT" SIZE="50" NAME="e-mail:01:\w+@\w+\.[\w\.]\w">

           This will tell TECForm that e-mail should concist of a string
           mached by the regular expression:
           \w+@\w+\.[\w\.]+\w
           what should be a reasonable regex for an e-mail adress.
           If the string does not matcg error 01 will be set.

              A litle regex tutorial

           To help you a litle bit on your way with regular expressions,
           i want to tell you a litle bit about the basics of regular
           expressions, i will be in no way complete, it will be more 
           of a quick refference, than a tutorial, but it should help
           you a litle on your way in defining regular expressions,
           and believe me, you do want to use them.
           This tutorial is nothing more than a litle list of regular expression
           characters and simple constructs, look on the net for more complete
           descriptions on regular expressions.

           Regular expressions are a way to mach a string to a sertain form,
           in its simpelest form a regular expression 'Hi There' will match
           the string 'Hi there', however this regular expression is not of
           much use. 
           If you would want strings with value's 'A' 'B' 'C' and 'D' to match
           and other values not, you could use the regular expression '[ABCD]'
           telling to mach a single char with one of the value's ABCD.
           The same strings will be also matched if you use a range like this:
           '[A-Z]' 
           Fore some often used sets and ranges of characters there are
           some short writings:

           \s  is matched by anny whit char like a space, a tab, a cr or a nl
           \w  is the same as [A-Za-z_0-9] 
           \d  is the same as [0-9]

           There are also some special characters you could like to match:

           \n  The newline
           \r  The CR
           ^   The beginning of your field

           Sometimes it is usefull to do negated matching, when you
           would like to match any character but 'X' you could use:

           [^X]

           Finaly, sometimes you might want to match any char, in what
           case you should use a dot in your regular expression.

           Untill now we only talked about singel character matching,
           but most of the time you would want to match more than just one
           character. For this there are 3 important ways:

           * will match for 0 or more times the preceding single char
           regular expression, for example:
           \d* will match '1375' , but also '29' or ''

           + will do about the same, but will need at least one character,
           so:
           [^P]+ will match everythin that isn't '', and has not got a 'P'
           in it, so 'Hi There' and ' ' will match but '' or 'WHATS UP' 
           will not

           ? means the preceding char should match one or zero times,
           '\s?' will match ' ' and ''

           There is also a way to do it more specific, by saying:
           'A{3,5}' you will match 'AAA' and 'AAAAA', but not 'A' or 'AAAAAA'

           I hope this litle comprehensiv tutorial is successfull in helping
           you to using TECForm to its fullest.
