weird / converge works in session but not inside function

depp:{[i]  {i+:1}/[{i~0};0]; :i} 

depp[0] / results in error 'i

although I is defined.

Please exuse but the function is useless but I am using it to illustrate I cant put converge inside the function. If you pull the stmts outside, then it works.

{[i]  {i+:1}/[{i~0} ;0]; :i} 

i is unknown in that bit +: applies to global. You can either init i before running depp or use :: within the function to set the global if its not already set
