CBASE [(#ch)](Btool) and

CBASE (#ch)(TinyToolkit)


BTool, TinyToolkit

The function CBASE finds the start address of the channel definition block which belongs to #ch. This is an area in memory where QDOS stores a lot of information about the channel, for example, which kind of device is connected to the channel.

The Btool variant returns the base of channel #1 if #ch is not specified.


The Pointer Interface modifies the structure of channel definition blocks for windows.

If you want to access these, preferably use WINCTRL instead of CBASE. See also CHBASE.

You can also use the CHAN_ <KeywordsC.clean.html#chan_>xx functions to look at the channel definition block.
