The UNIX distribution of GRTOOL contains the following files:
|grmacro.mac||EMME/2 macro used to produce link data file|
|grlink||Shell script for performing link-to-grid conversion|
|grparam||Shell script for creating a graphic parameter file|
|grannot||Shell script for creating an annotation from a grid file|
|grlinka.awk||AWK program called by grlink|
|grparama.awk||AWK program called by grparam|
|grannota.awk||AWK program called by grannot|
|readme||Text file with last minute informations which may not be contained in the printed documentation|
Create a new directory ``
grtool'' and copy the GRTOOL distribution
files into it and add this directory to your command search path.
Copy the macro file grmacro.mac
into your EMME/2 application directory or into one of the directories that
appears in your E2MACROS variable, or, alternately, append the term
/grtool/?.mac'' to your E2MACROS variable.
The GRTOOL programs check the path directories to automatically find the location of corresponding AWK files. This autodetection may be disactivated by setting an environment variable GRTOOL to the directory in which the GRTOOL files are stored.
By default the GRTOOL programs call the AWK interpreter by the name
(which is the name used by the freely distributed Gnu AWK). A different
AWK interpreter can be used by defining an alternate name (such as
awk'' or ``
nawk'') in the environment variable GRTOOLAWK.
Note, however, that GRTOOL requires a so-called ``new version'' of AWK,
as described by Aho, Kerninghan and Weinberger in The AWK Programming
Language, Addison-Wesley, 1988.
