What does command "shape" mean in polstm.q?

[liutongwei]

Hi, I'm using KDB+ 3.5 and I find there is a command in line#89:

H:(shape H)#K;

It dose not work and report an error with "shape".

So I wonder whether the command shape can only be used in KDB+ with version above 4.0 or is there any code to calculate number of rows and columns of a table?

So sorry, I had defined shape as my own function, for 2d arrays with constant size - k)shape:{(#x),(#x[0])}

Will update the code, thank you for pointing that out, I usually have that in my pre-load file, inside q.q
