I have a requirement where in I need to pass Arithmetic Expressions (+,-,/) as constants to a subroutine.For ex:
constants:c_p type char1 value '+',
c_m type char1 value '-',
data:v_a type char1 value '2',
v_b type char1 value '6',
v_r type string.
v_r = v_ a + v_b.
In the above instead of + I want use c_p.Please help me out is there any other way in defining Arithmetic expresiions where I could use constants or variables instead of directly using these expressions(+,-).Thanks in advance.
