This has nothing to do with the awk language, it's a question for your OS so ask
it in an appropriate NG.

for a direct answer to your direct question use Ed.'s answer
for an indirect answer to your hidden probable question I'd say
first use a file then use source on it

a little PoC goes a long way cause it's hot:

your given env var:
-------------
$ export _BARF=888
-------------

the PoC script:
-------------
$ cat bhappy.sh
#!/bin/bash

### call thrice an awk script that might have a try at
### incrementing an environment variable
### this is the given env variable to play with
echo "Before anything goes: $_BARF"
_BARF=999
export _BARF
echo "Right after first fighting: $_BARF"
###
### this is the simple mind awk to do just what to do
###
cat<<EOF>bhappy.awk
BEGIN{
x=ENVIRON["_BARF"]
x+=101
ENVIRON["_BARF"]=x
printf("\n\tin awk, x=%s, envB=%s.\n",x,ENVIRON["_BARF"])
}
EOF
###
cat<<EOT>bhappy2.awk
BEGIN{
x=ENVIRON["_BARF"]
x+=101
printf("export _BARF=%s\n",x) > _fout_
}
EOT
###
awk -f bhappy.awk
### wont work as is
export _BARF

awk -v _fout_="/tmp/_barfmeup" -f bhappy2.awk
. /tmp/_barfmeup
### might and magic
awk -v _fout_="/tmp/_barfmeup" -f bhappy2.awk
. /tmp/_barfmeup

###
###
###
echo "There was a showdown this place: $_BARF"
-------------

just counting cards:
-------------
./bhappy.sh
Before anything goes: 888
Right after first fighting: 999

in awk, x=1100, envB=1100.
There was a showdown this place: 1201

My alexbank_distribute_branches.awk does not produce the value to
codeinsidebat variable using that statement :

ENVIRON["codeinsidebat"]=codeawk

OK, might be, no idea what this 'batch' shell is nor what "OS"
(or pushed-up WM) you use it on, and that's a secret you seem
eager to keep, more than 3 weeks without a wink of an eye...
Hence now "@goto Ed-answer" ;-)

Your question relates to how your batch language works; specifically, what
batch language syntax is necessary to transfer the output from a batch
script into an environment variable.

This is a question for a Microsoft Windows scripting newsgroup, not
comp.lang.awk. You might find the proper forum in the microsoft.*
newsgroups.

Sorry, but I'm not a CMD.EXE batch scripting expert.

Now that we both wrote the same answer while using slightly
different "proxemies" it'd be interesting to know (probably in
January or so) which one gave the OP the final incentive hint ;D)
