I am trying to create a file with record size >32K. I am using this:
keyed "myfile",[1:1:16:"+"],0,-50000,opt="X"
This throws an error 41.  What am I mssing?

Mike King:
Set the record size to -30000 and use the OPT="X" (as you have specified).

The -30000 indicates that internally the system will split the records into 30000 byte chunks each linked together due to the OPT="X".

michaelgreer:
Thanks Mike. Not sure I would ever have figure *that* out.  :P  Now, I just did keyed "myfile",[1:1:16:"+"],0,-30000,opt="X".  I dimmed a$(35000).  When I write to a channel with myfile opened - write(lfo)*,a$  - I get an error 1.

Mike King:
What version PxPlus are you using?  I just tried this here and it worked on all supported release (PxPlus 2018 v15 -> PxPlus 2021 v18).

Well now, that may be the issue. I am on 10.20. Not supported there?
