Run Exe file from tcl macro

Hi,

I have converted .tcl file to executable (.exe)  file format. (The macro(.tcl) which works on Hypermesh )

Is it possible to call the .exe file from another .tcl macro?

exec [ file normalize 'c:\\hm\\Runexe.exe' ];

Or

Is there a way to secure the code?....Binary format or something...

Regards,
