Hi Barb:
Adagio works that way to be compatible with ACCPAC Plus.
However I agree with you. As Adagio moves away from Plus compatibility, it would be good if there was a option in the Company Profile offering "All Codes as Upper-Case". This will be especially useful for new clients that have never heard of ACCPAC Plus.
I suspect that the development team has this request somewhere in their list of "to-be-considered" topics.
