probably around 8 or 16 levels of nesting, depending on your system.

If the \fIexpr\fR evaluates to a non-zero \fBINT\fR, or a non-null
\fBSTRING\fR, then the \fBIF\fR portion is considered true, and the
\fIt-commands\fR are executed. If \fIexpr\fR evaluates to zero or
null, then the \fIf-commands\fR (if the \fBELSE\fR portion is present)
are executed. If \fIexpr\fR is not of type \fBINT\fR or \fBSTRING\fR,
then it is an error.
If the \fIexpr\fR evaluates to a non-zero \fBINT\fR, a \fBDATE\fR that

that is not 1990-01-01@00:00, or a non-null \fBSTRING\fR, then the
\fBIF\fR portion is considered true, and the \fIt-commands\fR are
executed. If \fIexpr\fR evaluates to zero or null, then the
\fIf-commands\fR (if the \fBELSE\fR portion is present) are executed.
