Re: Passing a Char to a Varchar in RPGLE Procedure Interface

Alan,

I find that hard to believe. How would the procedure do that? If a CLLE
program calls the procedure and passes a parameter by value, the value is
copied to the stack and the procedure receives that copy. What you imply
is that the procedure would somehow 'know' whether a passed parameter is
an actual varying length field or that it is a fixed character field that
needs to to be converted first.

Now, if you call from RPGLE the compiler will know from the prototype that
the procedure expects a varying length field, so it can add code to
convert the parameter to a varying length field.

I don't think that what Mike wants is possible. My solution would be to
have an extra procedure, especially for use from CLLE, with a fixed length
parameter. All it has to do is call the other procedure; then the
conversion will be automatically added by the RPGLE compiler.

Re: Passing a Char to a Varchar in RPGLE Procedure Interface

The procedure will do it for you. If you are passing by value, when you
pass a char it will automatically map to varchar. The only other thing

that

you need to do is to include the option *Trim to cause the value to be
trimmed when it is passed so you get the actual length.

This mechinism would work from CLLE or RPGLE.
