Return Calculated value of S. See also: valstr() Description First of all S is compiled. If there are errors while compiling a runtime error occurs which can be catched with the common methods. If compiling was successful the procedure is different depending on how the NV runtime flag is set: NV 1 (only numeric value = default) In this case a runtime error occurs too if it is not a numeric constant (number, date, time). No calculations are effected. NV 0 : The compiled expression is calculated. Thereby as standard functions as all functions of the module can be accessed. Above all this mode is dangerous if S is an (unchecked) input of the user! User comments: Write a comment: Name EMail Subject Text (Switch mode) Choose between the normal and the advanced editor.
