conventions for this purpose. C-Kermit 7.0 lets you provide lists of
filename patterns that are used to separately determine the file type

C-Kermit 7.0 adds limited support for floating-point numbers (numbers
that have fractional parts, like 3.141592653). This support is provided
through a small repertoire of functions and in Boolean expressions that
result to \ffpround(xxx,0) (to round).

Two floating-point constants are provided:

characters) is treated as substring notation in \s(name), but is

8. USING OTHER FILE TRANSFER PROTOCOLS
In C-Kermit 7.0, alternative protocols can be selected using switches.

+ protocol-selection switches is described in [640]Section 4.7.1.
Example:
send /binary /protocol:zmodem x.tar.gz
where a keyword (rather than a single letter) specifies the function,
and if an argument is to be included, it is separated by a colon (or
equal sign). Most of the new extended-format command-line options are

Where the C-Kermit 7.0 binary might be anywhere from 1 to 3 million
bytes in size, the G-Kermit binary ranges from 30K to 100K, depending
In such cases G-Kermit might be preferred since it generally starts up
faster, and yet transfers files just as fast on most (but not
necessarily all) kinds of connections; for example, it supports

G-Kermit is also handy for bootstrapping. It is easier to load on a new
computer than C-Kermit -- it fits on a floppy diskette with plenty of
diskette on Xenix with "dosread", and then use G-Kermit to receive
C-Kermit (which does not fit on a diskette). If diskettes aren't an
option, other bootstrapping methods are possible too -- see the

First, some missing acknowledgements for C-Kermit 6.0: JE Jones of

as "If all characters in string2 are also in string1, 0 is returned."
398 Copying \ffiles() results to an array before is not required as of
- C-Kermit 7.0 (see [647]Section 7.3).
+ C-Kermit 7.0 (see [650]Section 7.3).
403 In "(\%a + 3) * (\%b 5)", a minus sign is missing between b and 5.
407 C-Kermit 7.0 no longer supports multiline GET. Change
"get, \%1, \%2" to "get {\%1} {\%2}" or "get /as:{\%2} {\%1}".
