Hi, I am trying to send strings from Mathematica to C via MathLink. I have been trying now for two days to accomplish this seemingly simple task. Much of the problem stems from the absolutely hopeless documentation for MathLink functions. If Mathematica were free, one might sigh and accept the kindness of others in making code available. However, Mathematica is (very decidedly) not free. Is WRI going to turn into another monster like Micro$oft? So much for venting spleen. Does anyone have any examples of C code that implements string transfer between Mathematica and C, in both directions? If you do, please make clear what the types of the variables must be (this is an area where I came to grief by assuming that the documentation is accurate!). Many thanks in advance. Roger Mason
