.SH SYNOPSYS
.nf
.if n \{\
.ft B \}
.if t \{\
.ft CR \}
#include "abl101.h"

.fi
.SH PARAMETERS
.TP 20
\fIOper\fP
The unary operator number.
.TP
\fIExpr\fP
Expression.
.SH DESCRIPTION
\fBcreateablunaryexpr\fP creates the unary operator expression
\fIOperator\fP \fIExpr\fP. \fBcreateablbinexpr\fP combines
eventualy the operator of \fIExpr\fP with \fIOperator\fP.
The expression pointer \fIExpr\fP MUSTN'T be used after 
the call to this function.
.br
.SH RETURN VALUE
\fBcreateablunaryexpr\fP returns a pointer to the new operator expression.
.SH ERRORS
.if n \{\
.ft B \}
.if t \{\
.ft CR \}
"ablcreate: bad operator xx !",
.ft R
.RS
\fIOperator\fP must be defined and must be a unary operator.
