Basic Subfile update code

[philk12]

HI I am used to doing a subfile update having the user place an X next to the line they want to update and then displaying this record on a separate screen, allowing the update.

Now I have to allow them to directly change the data on the line I am not sure of the code sequence.

Perhaps someone has some basic code that does this or could do a walkthru on this?

Thanks,
Phil

the key here is the command READC (read changed record)

READC FORMATNAME

this will return those records from a subfile that have been changes while on the screen - i.e. the option field has been updated

loop through these records and process each one as appropriate

keep in mind that if someone puts X in the select field and then replaces this with a blank then this will be returned as a changed record - you therefore have to check the value of this field and go straight on to the next record if the select field is blank

forgot to mention - you can't easily update the values on the screen dynamically - if the changes need to be displayed straight away in the subfile then you have 2 choices

1) repopulate the subfile
2) use UIM lists instead of subfiles
