Re: How to get length in CLLE

call an rpg with 2 parameters: MyClVar and MyClVarLen.
in the rpg

MyClVarLen = %len(MyClVar)

that should work

Thanks for your reply here however I do not want to use RPGLE to get lenght.
I want it in CL only.
Is there any way to do it?

BTW - According to the test i just did it was far faster to type "How to get length in CLLE" into google than it was to open a new post in code400. And that's without the lag of waiting for answers ...

Re: How to get length in CLLE

That reminds me an old trick I want to keep you informed of. I use it from time to time to retrieve the length of a CL var.

I use RTVMSG along with message Id CPF9897 to retrieve the length provided that the variable is up to 512 bytes long. The length must be 5,0 field.

             DCL        VAR(&LEN) TYPE(*DEC) LEN(5)
             DCL        VAR(&PARM) TYPE(*CHAR) LEN(512) VALUE('MyValue')
             RTVMSG     MSGID(CPF9897) MSGF(QCPFMSG) MSGDTA(&PARM) +   
                          MSGLEN(&LEN)

In this example, the CL will return 7 which is the contents length of &PARM field.

However the Gary's suggestion above is certainly much better.
