System File Creation Macro

Attention : This code requires administrator privileges.

This macro creates a physical file on the server if it does not already exist. It handles two addressing modes: either by a full path (fullname), or by a directory/filename combination. It relies on the 'X' command to execute a system 'echo', which requires the XCMD option to be enabled. It also depends on probable external macros (%AHGtempdir, %AHGblank).
