expect script - simple proc function

[davidbelarus]

Gentlemen

i am converting my code to use proc and as proof of concept making basic proc functions:

this code gives this error: wrong # args: should be "printer a b c"
while executing
"printer { $brand $version $name }"


+++++code+++++
#!/usr/bin/expect -f

set brand 100
set version 1200
set name "hr20"

proc printer {a b c } {
puts "$a $b $c"}

printer { $brand $version $name }

made progress.

a few that work:

#taken from online example
proc printArguments args {
foreach arg $args {
puts $arg
}
}
set david "good person"
printArguments 1 2 3 $david

+++++++++++++++++++++++++++++

proc printer {a b c } {
puts "$a $b $c"
}

#set sum [plus $num1 $num2]
printer 1 2 3

+++++++++++++++++++++++++++++
