Hello. i'm new to asm programming and started with FASM because of its relative simplicity. i use windows 7 64bit. i currently write basic programs. i would appreciate some help on where to learn better especially in the field of win64 asm which is quite strange compared to 32bit. thanks in advance.

Be sure to get Feryno's FDBG to debug your effort!
