OK,
: rwtable(n,s,w,_,r) : _
Where:
• n: the table size
• s: the initial table content
• w: the write index (an int between 0 and n-1)
• r: the read index (an int between 0 and n-1)
So « w » and « r » must be of type « int » , correction here :
recIndex = (+(1) : %(maxSamples)) ~ *(btn) : hbargraph("[2]rec_index", 0,
maxSamples) : int;
This does compile (but I’ve not tested final result)
