Another idea, similar to one proposed below in your summary, but
simpler, I think:

Send the output strings to your batch file via replaceable parameters
(e.g., replaceable parameters %1 and %2 set to become your strings,
then invoke batch program by BATCH %1 %2).

Within the batch program, include ECHO %1 %2.

For example,

    SET %1=Hello
    SET %2=world

would appear somewhere after obtaining the strings.  Say the batch
file is HELOWRLD.BAT.  Start it by typing or calling HELOWRLD %1 %2.
Then, in HELOWRLD, the line

    ECHO %1 %2

yields "Hello world"; similarly, ECHO %1, %2 yields "Hello, world",
etc.

I am using two environment variables here, but no concatenation or
temporary files.  Perhaps you will find this less "clumsy".
