How to read a comma-delimited file using Mentor and produce a fixed format file

The spec file CSVINPUT.SPX can be used to read in a delimited file and create a fixed format file and a listing of where data variables are now located.CSVINPUT.DAT is the comma-delimited file to use with this spec.

Make appropriate changes and then run Mentor.

Modify the out options define to change the format of the output file to any type of file desired.

Make sure that the Length is >= the needed output length, which will probably be larger than the input length.


Also make sure Maxfields is set to >= the number of different data fields in the input record.

Another example that can be used is the delimitedexample.zip file. This is a simple example thatreads in delimited files, creates fixed files,creates and modifiesa map, and forces consistent layouts with different delimited files.
