acl_open_script_file

	file_ptr.sp.v = acl_open_script_file_c(file_name.i1a.r, mode.i1a.r,
					       actual_file_name.i1a.r)

	This routine opens an Accelerator Command Language (ACL) script
	file.

	file_name	 null terminated file name
	mode		 open mode for passing to fopen
	actual_file_name actual file name used

	This function returns values as follows:

	NULL			file not found or open failed
	otherwise		file pointer

	This function requires the following include files:

	ul_acl_h:acl_h, acnet_errors_h
