Protect a section of a line in JCL.

Hi,

When we open a JCL in edit mode, I would want to protect some columns.

for example:
I would want to pass a control card value from JCL to proc as,
2008 11 24

In edit mode, Can I protect (not allowing to edit ) the column '5' and '8'.

I'm sorry, if the question is illogical.

If a column is low-values (X'00'), edit will skip over that column. That's a very kludgey way of doing it. Maybe if you explain why those columns need to be "protected", someone can offer a better solution.

Those who don't know the format for the control cards should not be allowed to edit them. Programs should check the control cards for the proper format before using them. Or set up a REX or CLIST for changing the control cards. In my shop control cards are always in a separate library from the JCL so stupid people don't mess up the jcl.

Its been handled programatically, but I am trying to find ways in preventing the abend at the point of entry itself.

Just wanted to know, if there is something existing and I am not aware off.

Hello,

If "Its been handled programatically", how/why is ther an abend? What abend is happening?

If we know what problem you are dealing with, we may be able to offer better suggestions.

You can protect datasets so that they are only updated by certain program.

Display the information using a custom ISPF panel and when the user is done, update the JCL using your special program.
