need suggestions as early as possible....
ravs11,
I would suggest that you download Iczelion's tutorials. You will find a basic text editor in there. Then, if there are any functions you need help adding, you can always ask. Tutorials 33-35 are all editors with different abilities.
Using MASM 6.11 is not going to give you a problem as those examples do not make use of any advanced opcodes.
Also, in the MASM32 example set (exampl02) there is qikpad, a very nice basic editor. Be sure to look at that one. riched is also in there in exampl05, this one has more features.
