Can you use the DTML-VAR or DTML-CALL tag in ZSQL methods? Then it shouldn't be a problem.

The actions are more complex. There aren't just simple INSERT's or UPDATE's There are tables that should be opened, complex operations that should be made so I need an external program written for example in Tcl that will operate with lists, arrays and so on. I realise that a Python module would be just fine but I'm not familiar with Python. There should be some simple "exec myprogram" tricks that would allow execution of any external program. -- Constantin Teodorescu FLEX Consulting Braila, ROMANIA
