Re: using environment variable in .ptkrc file

[Christopher Hylands]

You can acces environment variables from Tcl with the env() Tcl array

cxh@maury 136% setenv FOO this_is_foo
cxh@maury 137% tclsh
% puts env(FOO)
env(FOO)
% proc printfoo {} {global env; puts env(FOO)}
% printfoo
env(FOO)
%

    I want to permlink some object code into Ptolemy, which I have been doing b
   y
    adding a line to the .ptkrc file.  But I have to explicitly declare the
    path.  I keep getting an error saying the variable doesn't exist if I try
    different variations using an environment variable like
    
    permlink $MYPATH/file.o
    
    or
    
    permlink expandPathName($MYPATH/file.o)
    
    ...
    
    How can I make this work?  Any suggestions?
    
    Thanks
