Dear Molpro user group, Does anyone know if I can use macros to define variables? For example: var_array=['myvar1','myvar2'] DO i=1,#var_array $$var_array(i)=i END DO show,myvar1 show,myvar2 This doesn't seem to work for me, and I was wondering if any knows if this is even allowed? Thanks, Yann Tambouret BU Chemistry
