About this document
Understanding ORG 100h in Assembly by mani_vlsi is a document available to read on EtoBox.
ORG 100h is a compiler directive that tells the compiler to calculate variable addresses starting at an offset of 256 bytes into the executable file. This is because operating systems store program metadata in the first 256 bytes of code segments for COM files. While EXE files are loaded at offset 0000 and use separate segments for variables, ORG 100h remains important for addressing variables when working with COM files.
