Re: RPGIV MoveA issue.

[Kevin Howcroft <kevinh@xxxxxxxxxxx>]

A few years ago I had a similar problem,
does not matter who looked at the code, the parms kepts getting messed up.

The only work-around I resolved to in the end was to
MOVE the parm-fld  into another new-field,
then reference that new -field throughout the program.

just my experience.
