print in a specfic location TCL

Is there any way to print argument in a specific location? I tried to use the below command but each argument depend on the previous one.

puts [format "%0s%20s%30s%40s" $check $runtime $cpus $result]

That's mean if $check is long name all the other data will be shift accordingly. Is there any way to determine the specific location to puts the var?

You didn't indicate how you would like to resolve the situation when a string is too long to fit the allotted space. Assuming you want to cut off the tail of the string, you can specify a maximum length:

puts [format %-10.9s%-10.9s%-10.9s%-10.9s $check $runtime $cpus $result]

The - will anchor the strings to the left, 10 specifies the field width and 9 limits the number of characters printed.

Demo:

set check "longcheckname"
set runtime "forever"
set cpus "all"
set result "passed"
puts [format %-10.9s%-10.9s%-10.9s%-10.9s $check $runtime $cpus $result]

Result:

longcheck forever all passed
