I really don't understand what you don't understand ;)
Here is an example where a module is used and variables are set and files are
processed based on the data returned by the module. I think this is an
example of what you're asking.
bundle agent check_user_files
{
vars:
!dotFilesFound::
# Put all users in /etc/passwd into the array "HomeDir", excluding
{
vars:
!dotFilesFound::
# Put all users in /etc/passwd into the array "HomeDir", excluding
# uids 1-199, nobody (-2), oracle (204), applmgr (205), paris (302),
# manpower (321) hpsmh (430), nfsnobody (65534, 4294967294) and
# ids (1000).
"HomeDirn" int => readstringarray(
"HomeDir",
"/etc/passwd",
"/etc/passwd",
"[^\n]*:[*x]:([1-9]|\d{2}|1\d{1,2}|-2|204|205|302|321|430|65534|4294967294|1000):[^\n]*"
,
":",
"300",
"12000"
);
!dotFilesList.!dotFilesFound::
"HomeUsr" slist => getindices("HomeDir"),
policy => "overridable";
dotFilesFound::
"dotFilesList" slist => splitstring("$(FindDotFiles.dotFiles)","
","800");
classes:
"dotFilesList" expression => isvariable("dotFilesList");
!dotFilesFound::
# FindDotFiles finds user initialization ("dot") files of interest and
returns
"dotFilesList" expression => isvariable("dotFilesList");
!dotFilesFound::
classes:
"dotFilesList" expression => isvariable("dotFilesList");
!dotFilesFound::
# FindDotFiles finds user initialization ("dot") files of interest and

"dotFilesList" expression => isvariable("dotFilesList");
!dotFilesFound::
!dotFilesList.!dotFilesFound::
"HomeUsr" slist => getindices("HomeDir"),
policy => "overridable";
dotFilesFound::
"dotFilesList" slist => splitstring("$(FindDotFiles.dotFiles)","
","800");
classes:
"dotFilesList" expression => isvariable("dotFilesList");
!dotFilesFound::
# FindDotFiles finds user initialization ("dot") files of interest and
returns
# them in the cfengine variable "dotFiles". A module is used because
cfengine
# doesn't support file_select with an edit_line promise.
"dotFilesFound" expression => usemodule("FindDotFiles","");

dotFilesList::
"$(dotFilesList)"
comment => "GEN002560",
edit_line => dot_file_check,
edit_defaults => no_edit_backup;
