assigning strings in conditional expressions

[hariceg]

Hi all,

I have a newbie question I am trying to assign a string to a variable in a conditional expression as follows

set range_a "5:4"
set range_b "3:2"
set range_c "1:0"

set range [expr ($i==0) ? $range_a : ($i==1) ? $range_b : $range_c]

I get the following error

unexpected operator ":" without preceding "?"
in expression "... ? 5:4 : (1==1) ? 3:2 : 1:0"
(parsing expression "(1==0) ? 5:4 : (1==1) ...")
invoked from within
"expr ($i==0) ? $range_a : ($i==1) ? $range_b : $range_c"

It is basically not treating range_a/range_b as strings - Could you please suggest a way to get this to work?

Thanks a lot in advance!

try escaping the colon: "\:"

Hi bong - escaping the colon didnt work - The following did work though

set range [expr ($i==0) ? \"$range_a\" : ($i==1) ? \"$range_b\" : \"$range_c\"]
