In "Classic" REXX a call of the function STREAM in the format
name=stream( fileName, "c", "QUERY EXISTS" )
never activates the NOTREADY condition. In Object-Oriented
REXX this call leads to the OS popup message box saying "Drive x: not
ready" if the statement AUTOFAIL=NO is missing in the CONFIG.SYS.
[Tested with OBJREXX 6.00 12 Jul 1996]
[Fixed in OBJREXX 6.00 26 Feb 1997 and newer versions (included in WARP
4 Fixpack #6)]

You can use the statement
curSize = stream( testFile, "c", "QUERY SIZE" )
to get the current size of open files on HPFS-formatted drives. Note that this is not possible for files on FAT-formatted drives (see also Copying open files).
