Problem:

Added an assembler program to my project.  However, when I try to compile it, the COMPILE option is grayed out.

Also -

I do not have ASSEMBLER COPYBOOK as an Associated Type on the General tab (Extensions tab) on the Build Settings for Project screen

I do not have an ASSEMBLER tab on the Build Settings for Project screen

How can I set these items up and compile my assembler program?

Resolution:

Under Mainframe Express v2.5, the ability to assemble source code is a seperate license.  You need to license and install the Assembler piece in order for any of the above to work.
