Re: Called RPG returns MCH3601

Hi Jon
I have defined parameter record at 01 level, it seems as:
01 param-list-1.
     02 envg            pic x.
     02 imgmov-1    pic x(436).
     02 enmsg          pic x(79)
     02 enout           pic x.
i have seen in the RPG
                                           *ENTRY      Plist
                                                                parm  envg
1
                                                                parm  imgmov
                                                                parm  enmsg
79
                                                                parm  enout
when i debug the RPG prog and display the value in parameter list i see the
my values for the first record but when it comes to second record
i only see the values are same as mine for imgmov, enmsg ,enout parameters
but RPG returns MCH3601 for the first parameter envg.
