Re: Word too long

[Mark L. <la...@mi...>]

Just for clarification, the limit is not on the environment variable
length (since env vars are shell independent). The limit is on the input
command line of tcsh. If you append to PATH,

 setenv PATH ${PATH}:/blah/blah

and path is already about 1000 characters, then this command will fail,
since the whole line expands to more than 1024 characters.  In tcsh
(i've got 6.09.00), edit "config_f.h" and change it to read
'#define
BUFSIZE 0x10000.' and recompile.
