|Syntax||HPUT [#ch] length [ , access [, type [, dataspace [, extra ]]]]|
This command allows you to set the various parameters which are contained in the header of the file attached to the specified channel (default #3). The command will use the supplied parameters to set the required information. If the specified channel is not open to a file, then an Invalid Parameter error is reported. The information which can be set is as per HGET.
You will not be able to compile this command with Turbo or SuperCharge due to the fact that it alters its own parameters.
