The upcoming e4thcom version supports conditional transfer code after #ifdef name
, e.g.
\ example: skip the rest of the file if test is defined
#ifdef test \\
\ example define test unless it's defined
#ifndef test : test ;
\ example: load PD_DDR unless it's defined
#ifndef PD_DDR \res MCU: STM8S103
#ifndef PD_DDR \res export PD_DDR
The change will be added to codeload3.py
(update to Python3 in #390) and the new version will be the new default. The Python2.7 version will be preserved as codeload2.py.

The following rules apply:
- the conditionals
#ifdef <name>
or#ifndef <name>
have to be the first word on a line - ordinary STM8 eForth console input may follow a conditional
#require
,#include
,\res
or\\
may follow a conditional and have to be the first word on a line in all other cases
