a.k.a. Don Cruickshank. [L1 ] I've worked in IT for over 20 years and since 1989 as a contract analyst/programmer/developer/etc. I've been developing in Tcl/Tk since the late 90s.
My experience is (mostly) in Unix and Microsoft evironments, largely with database development.
I live in the pretty city of Bristol in the south west of England, with my wonderful wife, three beautiful children, strange cat and a lurcher pup.
Some of the (many) things I love about Tcl.
1. True boolean test on a non-bool value (Double toggling a boolean to convert it to a true true value). The business is in the "db eval" statement using !!
proc SomeTest {x y} {
if {$x > $y} {
return [expr "22 / 7"]
}
return 0
}
....
db eval "update Stepper set IsActive = [expr "!![SomeTest $x $y]"] where ....."2. Boolean toggle
set a 0
set a [expr "!$a"]
set a [expr "!$a"]
