On the command line in the editor, just use the name of the

macro and list the paramters behind it. E.g. if you have a

macro called FINDALL and it expects 3 parameters you would

specify in the commandline: FINDIT parm1 parm2 parm3

When you code the MACRO the first line should be like:

Address ISREDIT "MACRO (parm1 , parm2, parm3)".

Since you are working with REXX you could have used:

Address ISREDIT "MACRO ( parm )"

You then parse the parm like this:

Parse (UPPER) Arg parm parm1 parm2 parm3
