# op\_plain\_offset

Convert operand to an offset (for the explanations of 'ea' and 'n' please see [op\_bin](https://docs.hex-rays.com/8.4/developer-guide/idc/idc-api-reference/alphabetical-list-of-idc-functions/696)()) base - base of the offset as a linear address If base == BADADDR then the current operand becomes non-offset Example: seg000:2000 dw 1234h and there is a segment at paragraph 0x1000 and there is a data item within the segment at 0x1234: seg000:1234 MyString db 'Hello, world!', 0 Then you need to specify a linear address of the segment base to create a proper offset: op\_plain\_offset(to\_ea("seg000", 0x2000), 0, 0x10000); and you will have: seg000:2000 dw offset MyString Motorola 680x0 processor have a concept of "outer offsets". If you want to create an outer offset, you need to combine number of the operand with the following bit:

\#define OPND\_OUTER 0x80 // outer offset base // Please note that the outer offsets are meaningful only for // Motorola 680x0.

success op\_plain\_offset(long ea, int n, long base);
