The function returns the INTEGER address of the downloaded file stored in
memory. The memory can be released by a call to RELEASE_STORAGE@.
FILESIZE is the size of the file that is to be downloaded. If this value is
zero then the function returns zero and the size of the file is the returned as
the new value of FILESIZE. The returned error code ERROR is zero for success.
An error code value of 1 (one) indicates that FILESIZE was too small so that
only part of the file was stored. Error code values greater than 1 (one)
indicate total failure with the function returning a zero address.
The returned address can be used to access the file by using FTN95 intrinsics
such as CCORE1(addr).
