[Dev-C++] Re: OT: Long command-lines

[Per W. <pw...@ia...>]

While the poor command.com is limited to 128 characters, thats no problem
for 32-bit programs.

cmd has a limit of just below 2kB and Win32 itself allows 32kB.

Any xx.com programs hare ancient MsDos history, since they are limited to
64kB code etc, by ising original CP/M file format.
