Hi

I am a new member and have started to play around with dos again after going astray for many years. In the past I have used A86 and now would like to use fasm.
The source snippet below works fine in A86 and lea points to ds:0102 which is where the start of image resides. But in fasm lea points to ds:0066 which is wrong. It looks as though I am using the wrong syntax. Help please and what is the best learning tool for fasm syntax.

You supplied 100 decimal as argument of "org", should be hex Wink

Yes that was the problem thank you. The following 'h' was not needed with A86 so I will have to watch that.
