does not seem right to me.
conventionally you would just use echo -e and \n for newline

echo -e 'dim a as string\na="coffee:tea"\nprint a'|gbs3 -

It's like the idea to use : for lf was by someone who was not aware of the
-e arg of echo to process escapes.
I guess we just need to add to the wiki...
A colon : is translated to \n unless you use the - argument.
or replace each : with &chr$(58)&


but then your example Tim..
echo 'dim a as string:a="coffee:tea":print a'|gbs3

fails if you use - or not.
I think there are more problems than benefits to the conversion of : to lf
And i don't think it's needed as echo -e and '\n' would be the conventional
way.

I think in my fork i will remove the conversion as i don't like it and I
didn't even know you could use : for lf.
and I'll be sure to use echo -e and the - argument in any gbs3 scripts for
public use.
