Shortened Application name

I have noticed that when scripting Acrobat, when I put in the tell statement for “Adobe Acrobat 7.0 Professional”, it changes on compiling to “Adobe Acrobat 7.0 Profe#5DC”. It works, but I have been curious why the compiler does this. Anyone know?

tell application "Adobe Acrobat 7.0 Profe#5DC"

Model: Mac G5 OS 10.3.9
