Re: Checking datatype of CHAR variable in 4GL

I wrote one not too long ago: FUNCTION DUMMY WHENEVER ANY ERROR CONTINUE END FUNCTION FUNCTION not_an_int(incoming) DEFINE incoming INTEGER RETURN status END FUNCTION FUNCTION DUMMY2 WHENEVER ERROR .... END FUNCTION Then merely... IF not_an_int(char_var) THEN ........ Note - I wouldn't swear to the WHENEVER syntax - I may have that slightly off. Of course I don't have the function handy... The trick is in to getting the compiler to not check status for your conversion. Passing the char variable to a function which expects an int implies a conversion and status gets set if it fails. cheers j.
