+DESCRIPTION
+\fIImaccess\fR is a boolean intrinsic function returning true ("yes") if the
+named image exists.  The function will return false ("no") if the image doesn't
+exist, or if no image extension is supplied and the image name is ambiguous.
+\fIImaccess\fR can only be called as a function in an expression, not as a task.
+.ih
+EXAMPLES

+
+.nf
+    if (imaccess ("dev$wpix"))
+	imheader ("dev$wpix",long+)
+    else
+	error (11, "Image not found")
+.fi
+
+2. Tell if a image exists.
+
+	cl> = imaccess ("dev$pix")
+.ih
+BUGS
+An optional second argument should be added to test whether the named file
+can be accessed for reading or writing.
