[Swftools-common] Linear actionscript motion

[Daniel]

I know perhaps this question is a very stupid question, but I'm very new
to swftools.
I've started to use actionscript code and notice this.
If I run a normal swftools script like:

.frame 1
    .put something

.frame 100
    .change something

It do the rest of movements between frame 1 and 100, but If I do this:

.frame 1
    .put something

.frame 100
    .action:
       something._X=xxx;
       something._Y=yyy;

It change the something object suddenly at frame 100.

My question is simple: Can actionscript do the same as swfc scripting ?

Thank you very much and sorry for my english.
