Eval method
Evaluates a string as an ACL expression and returns the result of the evaluation as a string. The string to evaluate must contain an expression. For example:
2+2
or
tbl_oid_cell(oid_caret(),oid_caret_pos())
Variable substitution in the expression string occurs on the ACL side of the AOM interface, not on the client side. You can include ACL variables in the expression string. However, do not include variables native to the client program.
