          icont, iconc - Icon language translator and compiler

          icont [ option ... ] file ... [ -x arg ... ]

          iconc [ option ... ] file ...

          Icont translates Version 5 of the Icon programming language
          to an intermediate form, and link edits intermediate files
          to interpretable files.  Iconc does the same, but finally
          compiles to machine code.  Unless the -o option is speci-
          fied, the name of the linked file is formed by deleting the
          suffix of the first input file named on the command line.
          Option -x invokes the interpreter and passes the args to the
          Icon program.

          Files whose names end in `.icn' are assumed to be Icon
          source programs; files whose names end in `.u1' or `.u2' are
          assumed to be intermediate files from a previous translation
          (only one should be named - the other is assumed).  Unnamed
          .u1 and .u2 files are deleted.  The argument - signifies the
          use of standard input as a source file.

          The following options are recognized by icont.

          -c   Suppress linking and loading; preserve intermediate

          -m   Preprocess each `.icn' source file with the m4(1) macro
               processor before translation.

          -o output
               Name the interpretable file output.

          -s   Suppress informative messages.

          -t   Arrange for &trace to have an initial value of -1
               instead of 0 when the program is executed.

          -u   Issue warning messages for undeclared identifiers.

          To run either and interpreatable or an executable file, sim-
          ply execute it as a command.  The following environment
          variables - all numeric - affect execution:

               Initialize the value of &trace, overriding the transla-
               tion option -t.

               The number of i/o buffers to use for files, normally 3.
               &input and &output are buffered unless they are termi-
               nals.  &errout is never buffered.

               The initial size of the string space, in bytes, nor-
               mally 51200.

               The initial size of the heap, in bytes, normally 51200.

               The number of stacks initially available for co-
               expressions, normally 4.

               The size of each co-expression stack, in words, nor-
               mally, 2000.

               Turn on execution profiling of the runtime system.  The
               value of this variable specifies the sampling resolu-
               tion, in words.  If the value is zero, profiling is not
               done.  The profiling results are left in a file
               `mon.out' for interpretation by prof(1).

          If the -m option is used, line numbers reported in error
          messages or tracing messages are from the file after, not
          before, preprocessing.
          Integer overflow on multiplication is not detected.
          An interpretable file produced on one system will not work
          on another system unless the Icon interpreter is in the same
          place on both systems.

          Because of the way that co-expressions are implemented,
          there is a possibility that programs in which they are used
          may malfunction mysteriously.
