I'm trying to get a program from the EXOFAST library running, and when I ask GDL to run it, it gives this: GDL> barycorr % Compiled module: BARYCORR. % Procedure not found: BARYCORR % Execution halted at: $MAIN$ adding in the inputs changes it to give "Unexpexted token: pmra" (pmra is a variable in barycorr). I have the required plplot, gsl, and readline installed and have the other IDL libraries added into the GDL library on my Mac. What is going on? Fair warning, I'm a noob at programming stuff,...
