Tcl Script Learning IX: For Loop Learning

Lesson9:for-Cycle Learning

For {puts "Start", set I 0} {$i < 2} {INCR I; puts "I after incr: $i";} {
Puts "I inside first loop: $i"
}

Like C, there are three conditions.

; # Because The test is evaluated before the body,
; # this loop won ' t execute the body of the code.

For {puts "Start", set I 3} {$i < 2} {INCR I; puts "I after incr: $i";} {
Puts "I inside second loop: $i"
}
Do not meet the criteria to end the For loop directly

; # A while loop equivalent to the first for loop:

Puts "Start"; Set I 0;
While {$i < 2} {
Puts "I inside first loop: $i"
INCR i;
Puts "I after incr: $i";
}

INCR usage in while
