for more information.options()
is used by many programs for processing command-line options and is linked
from "ucode" files obtained from translating options.icn.IPATH environment variable. IPATH
consists of a sequence of blank-separated path names. The search is in the
order of the names. For example, on a UNIX system running csh,
results in a search for file names in link declarations first in the current directory, then in .setenv IPATH "../procs /usr/icon/ilib"
./procs, and finally in /usr/icon/ilib.$include are searched
for on LPATH. It has the same form as IPATH.IPATH and LPATH varies from
system to system.IPATH
and LPATH need not be set if ucode and include files are placed
in the same directory as the program files. See the next section.
-c
option to icont, as in
which translatesicont -c options
options.icn. The result is two ucode files
named options.u1 and options.u2. The .u1
file contains the procedure's code and the .u2 file contains
global information about the procedure. It is these files that a link declaration
such as
needs.link options
IPATH.-c

which translates and linksicont deal
deal.icn, a program that produces
randomly selected bridge hands..icn suffix removed (for example,
deal). On other platforms, the icode file name has the suffix
.exe in place of .icn (for example, deal.exe).
Scripts for translating and linking the programs are provided with distributions
for individual platforms. Instructions for building the programs contained
in separate packages are included with those packages.On other systems, it is necessary to rundeal
iconx with the icode
file as an argument, as in
(This also works on systems that support direct execution.) Note that the suffix (if any) need not be mentioned.iconx deal
thedeal -h 10
-h 10 instructs deal to produce 10 hands. PATH.
Ucode and include files are needed only during linking. They need not be
accessible when icode files are run.
