That was the problem.
I am trying a bit different route:
set teaList []
db eval ${getTeasToDrinkStr} {
lappend teaList [dict create \
Tea ${Tea} \
LastUsed ${LastUsed} \
Location ${Location} \
Randomiser ${Randomiser}]
}
set i 0
while {${i} < [llength ${teaList}]} {
puts [format "%d: %-30s %-10s %2s %d" [expr ${i} + 1] \
[dict get [lindex $teaList ${i}] Tea] \
[dict get [lindex $teaList ${i}] LastUsed] \
[dict get [lindex $teaList ${i}] Location] \
[dict get [lindex $teaList ${i}] Randomiser]]
incr i
}
This does what I want (I need the value of Tea to update the database), but
is there a better way?
