I believe this is due to some info being saved in the resource file, because I did this in the Command Window:

*- Started VFP6 SP5 w/SET RESO ON
lcText = [FUNCTION MyUDF()] + CHR(13)+CHR(10)+[RETURN "Hello"]
STRTOFILE(lcText, "TestSH.prg")
modi comm testsh      &&  syntax coloring, as expected.
modi file testsh.prg  &&  syntax colored, NOT expected.
set reso off
modi file testsh.prg  &&  no syntax coloring, as expected.
