Splus returns NULL

[Dennis Fisher <fisher@plessthan.com>]

Colleagues

This is probably remarkably simple but I cannot find the answer.  When a conditional statement tests as negative, Splus (version 7.0.0 running on RedHat Linux) returns NULL.

for example:

X <- T

if (!X) cat("hello")

returns NULL.  I have tested options(warn=-1) and options(echo=F) to no avail.  In R, the same commands return nothing.

Any ideas how to prevent the NULL returns?
