Re: [SPAM 1]Parameter prototype question

[Charles Wilt <charles.wilt@xxxxxxxxx>]

Prototypes will prevent the error your are describing.

Either you've found an IBM bug or more likely, you're not doing what
you think you're doing.

My guess, you've got the differing prototypes hard coded in multiple
places, instead of having it in a single source member that gets
/INCLUDEd.

The other possibility, instead of using CALLP to call with a
prototype, the code is using CALL with the PARM opcodes.

Last but not least, do you have the CONST or VALUE keywords on the
prototype and procedure interface that you are not showing?

HTH,
Charles Wilt
