Starting up IRAS90

IRAS90 comes in two forms. One is a monolith that is activated within the ADAM command language--ICL. The other comprises individual applications and is run from DCL (on VMS), or from the the shell (on UNIX). The monolith has the advantage that after the initial pause while it loads, all its constituent applications are available immediately. There is no pause while each new application is fired up. This is fine when you wish to run several applications and/or the same application several times. However, for single tasks it may be more convenient to run from DCL or the shell.

To run IRAS90 on VMS from DCL , just enter the command

     $ IRAS90

This executes a procedure setting up symbols for IRAS90's command names, and defines some logical names to make help information available.

The command to run the IRAS90 monolith is almost the same except you must be within the ADAM command language. This requires just one extra command, namely

     $ ADAM

You will see any messages produced by system and user procedures, followed by the ICL> prompt. Again there is a procedure for making the commands known to the command language, and not unexpectedly, it too is

     ICL> IRAS90

To run IRAS90 on UNIX from the shell, first ensure that you have a subdirectory adam within the directory identified by environment variable HOME. Then enter the command

     % iras90

This executes a script setting up aliases for IRAS90's command names.

In all cases you'll see a message telling you which version of IRAS90 is ready for use.
