Program Preprocessor?

[Jingwen Wang]

Hi, experts,

  I am going to design a program preprocessor for software transplant.
I need to substitute some of the Fortran calls for calls on the new
machine. I don't know which is the most efficient way to do this. I
have two options: design the preprocessor in C or in awk language. Can
someone tell me which is the best way to do this simple substitution
task? Or has anyone already done this similar job?

Thanks.
