Merge two text files (oh no, not again!)

Hello,

I'm new to this forum. I have always made good use of all the wise hints shown here. But this time I'm struggling with an issue that is driving me crazy.

I have two text files, I have to merge them based on the first column, resulting file must contain all record from the first file AND all records from the second one.

Are there clashing values? Is ";" the field separator ?
# 3  
No clashing values, and yes ";" is the Field Separator. I'm running AIX 7.1.0.0
The files look like in my above post. No hidden rows Smilie

I know how to get a merged file with just common records using AWK
Code:
awk -F\, '{FS=";"} NR==FNR {a[$1]; next} ($1) in a{ print $1";"$2".........

but here I need to have all records.

Thanks. It looks just what I need.
I'm checking the files (huge) and the output looks correct.
