Re: How to make two referencing sub-projection works?

[kshepherd]

f:{[xF] 
    g:{[h;xG] $[xG < 0; xG; h[.z.s; xG - 2] + 20]}; 
    h:{[g;xH] $[xH < 0; xH; g[.z.s; xH - 3] + 30]}; 
    g[h; xF] }; 
f[10];

Another option is to use .z.s to refer to the calling function when calling the other function.
