Editing Environment variable (section)

== Notes ==
{{Reflist|group="nb"|refs=
<ref group="nb" name="NB_CMDLINE">[[4DOS]] and [[MS-DOS 7.0]] set the length to 127 and insert [[ASCII 13|ASCII-13]] at this position, but [[Borland]] libraries set the length to the invalid value of 128 and do not insert an ASCII-13. For shorter command lines, 4DOS/[[NDOS]] and [[DR-DOS]] also insert an [[ASCII 0|ASCII-0]] after the ASCII-13, but not when invoked via [[INSTALL (CONFIG.SYS directive)|INSTALL]] directive; MS-DOS does not.</ref>
<ref group="nb" name="NB_ENVLEN128">Applications not coping properly with environment variables longer than 128 characters include [[CadStar PCB]], Checkit, Computer Select CD-ROM, RenderMan, [[VINES Network]], [[Windows 3.0]], and [[Word for Windows 6.0]].</ref>
