Condition codes are:

c

[n]a[e] – above (unsigned greater than). An n can be added for not and an e can be added for

“or equal to”

c

[n]b[e] – below (unsigned less than)

c

[n]e – equal to

c

[n]z – zero

c

[n]g[e] – greater than (signed comparison)

c

[n]l[e] – less than (signed comparison)

c

[n]c – carry flag set

c

[n]o – overflow flag set

c

[n]p – parity flag set

c

[n]s – sign flag set

c

ecxz – %ecx is zero
