Some issues Solved and Corrected about txquery HOT 4 OPEN

Thanks man Great Job...

Hi, i have an issue usinf string functions like UPPER o TRIM with fields float 
or int fields shows some extrange values, id tried to track the fail and found 
at line 3898 in xquery.pas the value of n always is 2 but with string fields 
the value is diferent, can you can help me to fix this issue?

Please atatch here a demo to test the issue you are having.  Have you tried to 
cast first the values to string and then pass them to the string functions?

Ok. I managed to resolve the problem. download updated_sources.rar, update the 
units and recompile both packages.

TXQuery_update_full contains all sources updated and extra some files.

*Fixed: when using a Float or integer field with a string function like UPPER, 
it returns strange values.

*Workarround: added LeftStr and RightStr lias functions for LEFT and RIGHT, 
because this functions can't be used in the field list of a select clause, etc 
can only be used in WHERE conditions.

*added some Alias functions as SubStr and MidStr.
*Small additions and fixes

All changes are marked with my alias 'fduenas'
