Code:

NumExc = 17
NumInt = 16

Count = (NumExc+NumInt)

rept Count n:0 ; invalid value
{
Interrupt#n: call Target
}
Target: mov cx,Interrupt1-Interrupt0

The same reason. rept is preprocessor directive, but all numeric constants defined by "=" are assembling time constants and are unknown when the preprocessor runs.

Changing "=" to "equ" fixes it:

Code:

NumExc equ 17
NumInt equ 16

Count equ NumExc + NumInt

rept Count n:0
{
Interrupt#n: call Target
}
Target: mov cx,Interrupt1-Interrupt0
