Hi All,  
The BCON, ICON and MCIP run ok, but the CCTM still has some problems.  
Below is the errors, please give me the suggestion if you know that or you have met similar errors.  
Thanks!!

As has been documented in the I/O APUI build-instructiuons [https://cjcoats.github.io/ioapi/AVAIL.html#cmaq](https://cjcoats.github.io/ioapi/AVAIL.html#cmaq) and has been repeated elsewhere on this forum: According to the ISO Fortran Standard, there are two “source formats” for Fortran source code – the older ( `f77` ) “fixed” format with code in columns 7-72 and continuation markers in column 6, and the ( `f90` ) “free” format, with source in columns 1-132 and ampersand (“&”) for trailing continuation markers, as well as a specification for code which is acceptable to both forms.

Since it is used by various models that use “free” format, the I/O API carefully follows the Standard in this regard, and uses the ISO-app[roved “both-form” format for its Fortran `INCLUDE` files.

> Some of the models—in particular, CMAQ and SMOKE however, do not—instead using a “fixed-132” format. The I/O API Makefile has a way of dealing with this; the commands
