Question: procedure error

i'm trying to run the following procedure:

> restart; with(LinearAlgebra);
> test:=proc(alpha, beta);
print(`output redirected...`); # input placeholder
Error, unterminated procedure
         testAssignTypesetting:-mambiguous(

           procApplyFunction(αcomma β),

           Typesetting:-merror(unterminated procedure))

> local  itype::integer, lambda1, lambda2 Delta;
print(`output redirected...`); # input placeholder
Error, unable to parse
Typesetting:-mambiguous(local,

  Typesetting:-merror(unable to parse)) itypeColonintegercomma

But i keep getting errors like unterminated proc, and unable to parse error with local and end proc...

any suggestions????thnx in advance..
