Error: symbol 'NUMBER_OF_SECTIONS' is undefined or out of sc

A bit more of context is needed, you did not show how do you use these macros.

Also, sometimes the first error that gets reported is actually a consequence of an error elsewhere, because of the forward-referencing. Please try assembling with higher "-e" setting to display information about more errors.

For example, a similar error shows up if I add the unbalanced "IF" near the end of a simple PE source:

Code:

include 'format/format.inc'

format PE GUI 4.0

ret

if 0

The error that gets reported when we show only one is the first one encountered, but this first error is in fact a consequence of an error elsewhere (the unbalanced "if 0" caused postponed lines to not get executed properly):

With the "-e100" setting the actual original error that caused the "avalanche" is seen at the end:
