Command line:wolframscript -file second.wls 2 3The result is Out[0], I don't know why. Thank you!
The output from D[rs0,x]; is suppressed, so % defaults to Out[0]. Best to avoid %.
D[rs0,x];
%
Out[0]
num = ToExpression[$ScriptCommandLine[[2]]]; num2 = ToExpression[$ScriptCommandLine[[3]]]; rs0=x^2; d=D[rs0,x]; ff[x_]:=Evaluate@d aa=ff[num+num2]; Print[aa]
Why is it suppressed when using command line, thank you very much!
Not command line specific. The ; and the end of the expression suppresses output even in a notebook.
;
Ok, thank you!
