Is tcsh 100% compatible with the plain-old csh [on Solaris 9]

Hi folks

There are about 200 csh scripts (I didn't wrote them). Do all those scripts run with tcsh without modification? Is tcsh 100% compatible with the plain-old csh?

$ which csh
/usr/bin/csh
$ which tcsh
/usr/bin/tcsh
$ uname -a
SunOS purzelse 5.9 Generic_117171-07 sun4u sparc SUNW,Sun-Fire-V440

Hi.

From the first line of the tcsh man page:

tcsh  is  an  enhanced but completely compatible version of the Berkeley UNIX C shell, csh(1).

There is almost no difference between syntax of csh and tcsh statements. tcsh is essentially csh plus the TENEX command line editor and history handler.
