You mean, a Scheme variable (inside TeXmacs) ? In this latter case, if your
Scheme variable is called 'name-of-the-file', you should write :
<<
<action|text|(system (string-append "acroread " name-of-the-file))>
>>

Or either, if the name of the file is contained in a TeXmacs variable 
inside the
document (i.e., the kind of variable you set using 
'<assign|my-variable|value>'),
then you can use (get-env "my-variable") from inside your Scheme code. So
you write :
<<
<action|text|(system (string-append "acroread " (get-env 
"name-of-the-file")))>
>>

For example, you can cut & paste the following markup in a TeXmacs 
document :
<<
<assign|var|123>
<action|abcde|(display (string-append "Hello!" (get-env "var")))>
>>

then when you double-click on the blue "abcde" text, you obtain :
<<
Hello!123
>>

on the TeXmacs console.

That would be great.
