Tcl question

[David Ma]

I have a tcl that has more message condition checks as following:

if  {***} then

{set mykill = TURE}

if {XYZ} then {

set mykill = TURE}

……………..

Is there a way that the first message hits the first IF statement then stop going to check the second or third IF statement and check the second message? It will save some message process time in the engine.

if {***} {
set mykill TURE
} elseif {XYZ} {
set mykill TURE
}

Use an IF- ELSE instead of just IF. Like so:

if {***} {

set mykill = TRUE

} else {

if {XYZ} then {

set mykill = TRUE}

}

Another option if the same field is being checked in all the conditions is to use the switch command.

switch -exact — $field_to_check {
“value 1” {action to take}
“value 2” {action to take}
…
default {action to take}
}

There are two other options besides -exact: -glob and -regexp.  The “–” marks the end of the options, and the “default” entry is the action taken if no match is made.

Thanks all!

I mean if the first IF statement match, then tcl will not check the second ELSE IF statement. the TCL will stop after the first IF statemnet and start checking the second message. something like using if {ABC is ture} then {  lappend dispList “KILL $mh”}

What Boris gave you above is exactly what you ask for.  If the first if statement evaluates true then the elseif will not be evaluated.  That is the purpose of elseif.
