tcl if condition not working

What is wrong with my following code. It wont execute.

$pre_event_date =0;
set halBirthMovie "Jan 12, 1992"

if{$pre_event_date == 0} {
        set halBirthMovie [clock format [clock scan $halBirthMovie] -format {%d %b}]
        set pre_event_date [clock format [clock scan $pre_event_date] -format {%d %b}]
        if{$pre_event_date != $halBirthMovie}{
            puts "Not Equal"
            puts "Equal"
        puts "Nothing"

RE: tcl if condition not working

Wrong is how you format the if-else command.

Your code will work if properly formatted:


set pre_event_date 0
set halBirthMovie "Apr 16, 1992"

if {$pre_event_date == 0} {
  set halBirthMovie [clock format [clock scan $halBirthMovie] \
      -format {%d %b}]
  set pre_event_date [clock format [clock scan $pre_event_date] \
      -format {%d %b}]
  puts "\$halBirthMovie  = $halBirthMovie"
  puts "\$pre_event_date = $pre_event_date"
  if {$pre_event_date != $halBirthMovie} {
    puts "Not Equal"
  } else {
    puts "Equal"
} else {
  puts "Nothing"

$halBirthMovie  = 16 Apr
$pre_event_date = 16 Apr
