Number format

Microprocessor manufacturers have chosen a variety of different formats for

representing hexadecimal numbers. [Some sort of formatting is essential,

otherwise a hex number starting with an alpha character could be confused with a

label or symbol name.]

DASMx

supports five different hex number format styles. These are summarised

in the table below, with an example in each case for the hex number F12C.

Number format numformat parameter Example

DASMx

chooses a default number format according to the CPU type setting. The

default choice can be overriden by a numformat statement in the symbol file. The

number format defaults for the processors supported by

DASMx

are given in the

following table.
