RE: [EXTERNAL] Calling an ILE Procedure from CLLE

[Greg Wilburn <gwilburn@xxxxxxxxxxxxxxxxxxxxxxx>]

I'm setting the variables to a fixed values in the CL...  The actual data values will never exceed 50 characters.

I just recall something goofy when you have CL Character variables over a length of 32.

Here's the actual code:

             PGM
             DCLPRCOPT  DFTACTGRP(*NO) ACTGRP(*NEW) BNDDIR(TBFBIND)

             DCL        VAR(&LOG) TYPE(*CHAR) LEN(50)
             DCL        VAR(&SUBJ) TYPE(*CHAR) LEN(100)
             DCL        VAR(&STMF) TYPE(*CHAR) LEN(1024)
             DCL        VAR(&TOADDR) TYPE(*CHAR) LEN(50)
             DCL        VAR(&CCADDR) TYPE(*CHAR) LEN(50)
             DCL        VAR(&MSG) TYPE(*CHAR) LEN(1024)
             DCL        VAR(&ERRID) TYPE(*INT) LEN(2)

             CHGVAR     VAR(&LOG) VALUE('/ftplogs/NYR000-20191007-95915.log')

             CHGVAR     VAR(&SUBJ) VALUE('This is a test')
             CHGVAR     VAR(&STMF) VALUE(&LOG)
             CHGVAR     VAR(&TOADDR) VALUE('*IT_STAFF')
             CHGVAR     VAR(&CCADDR) VALUE(' ')
             CHGVAR     VAR(&MSG) VALUE('*ATT')
             CALLPRC    PRC('Eml_Stmf') PARM(('001TBF') +
                          (&SUBJ) (&STMF) (&TOADDR) (&CCADDR) (&MSG)) +
                          RTNVAL(&ERRID)
             ENDPGM

Not clear. Are these variables coming into the CL as VarChar's? If yes, I
don't see the problem.

Assuming a two byte header and 1024 length field you would just pass and
declare as a 1026 byte field. Receive as a VarChar(1024) in your RPG.
