I don't think it is a good idea for your Ada knowledge to be a string :)

I don't recall 3.10 very well. Does GNAT.OS_Lib exist for that release? 
If so, Spawn will do these kinds of things for you. You use the program 
"command" and give it the arguments "/c desired-command arguments". For 
example, for renaming a file, you would pass the arguments

"/c ren " & Old_Name & ' ' & New_Name
