Which is better? (whatever "better" is)
This:
if {[info exists CHIPNAME]} {
set _CHIPNAME $CHIPNAME
} else {
set _CHIPNAME at91r40008
}
or this:
set _CHIPNAME [defaultval $CHIPNAME at91r40008]
# Std proc to be added
proc defaultval {varname defval} {
if {[uplevel "info exists $varname"]} {
return $varname
} else {
return $defval
}
}
