A method is described for creating computer programs to analyse text for compliance with a specified structure examples of such programs are command decoders and format checkers. The paper shows how analysis programs are easily produced by constructing a table directly from a specification of the intended data format and presenting this as input to a non-specific parser subroutine which has been written and is described. Facilities are included to execute user-written subroutines when key structures are recognized in the input. Programs have been written in PDP-11 and NOVA assembly language to implement the parser, and instructions for use of these programs, examples and listing are included. Author
