Hi together,
you know the member list that you get when you open a PO dataset under ISPF 3.4 with e for edit. You will then see the member list with the specific information. On the left side there are 9 underscores in which I (normally) enter the known lines of commandos. D for delete, s for edit... etc
Now I want to position the cursor in front of a member, enter a string (e.g. dis for display) and then press Enter. DIS is a sample and not the requirement. A REXX with the name 'DIS' should then be executed. So far so good. The REXX is executed.
But I need the dataset and member name, because I want to do something with the member.
Can anyone help me with this? Are there standard variables that I can query or where do I have to read in?
I hope I have described everything clearly.
Thank you very much for your help.
Regards
Punki |

See Arg keyword. Your sample can be as simple as follows:
| Code: |
/* REXX */
Arg parms
Parse Upper Var parms dsn '(' member ')' .
Say "Parm="parms; Say "DSN="dsn; Say "Member="member
Exit |

Hi Joerg.Findeisen,
yesterday I looked for so many possibilities and found nothing suitable.
Thank you very much. Everything works as desired.
Sometimes you just can't see the wood for the trees.
Thanks and best regards

Note that you can use the slash '/' as a substitution for the datasetname. That way you can give a parameter for the program where the datasetname is part of the string.
I.e linecmd in the 3.4 Datasetlist: listc ent(/) all
It is ok to overwrite part of the line. |

It can be even more simple.
| Code: |
/* REXX */
Arg dsn '(' member ')' .
Say "DSN="dsn; Say "Member="member
Exit |
Just a reminder:
- operator ARG is equivalent to PARSE UPPER ARG; it converts all parameters to uppercase, and performs parsing of the text string.
- operator PARSE ARG does the same without conversion to uppercase. |
