I read in the vbscript_to_powershell.doc from Microsoft site that PS does not support subroutines only functions. What is used in place of subs then?

Nothing. There's really no overriding reason to use a Sub instead of a Function

VBScript is apparently one of the few scripting languages that really differentiates between a sub and a function. In PowerShell, all code blocks that "do something" or return a value are considered functions. The other big difference is that in a .ps1 script, your functions have to come at the beginning of the script. In VBScript, they could be anywhere. But PowerShell processes the script file sequentially like a batch file and the function has to "exist" before it can be called.
