In FPC 3.0.4, {$MODE ISO} allows file variable notation
(filevar^.field1) and provided Get/Put calls (in addition to
Read/Write).
The downside to ISO mode is the loss of non-ISO features (strings,
etc).

To narrow down the mode, I tried using {$MODESWITCH ISOIO} to provide
just ISO-based I/O operations (while retaining the other "perks" of
FPC).
But this was flagged by the compiler with a:
"Warning: Illegal compiler switch "ISOIO"
and any file variable references (filevar^.field1) were flagged with:
"Error: Illegal qualifier"

In a current snapshot FPC 3.3.1, {$MODESWITCH ISOIO} is now recognized
(Thank you) as are the file variable references, however Get/Put calls
are flagged with a:
Error: Identifier not found "put"

Is the exclusion of Get/Put support within ISOIO an oversight, is it
being worked on,
or am I missing something?

Thank you
