Hello,
Check Re: Control Block
for changing the WHERE attribute of a block.
In your case, you want to set the WHERE condition for the cursor and this depends on a value or values you get from another block. In this case, it is best to give the user a way to either enter that condition or store the result you get from the other block in a variable and use that variable in your cursor.
You can use a parameter to store that condition and this will be local to the current form. If however you need to get that from another module, then you might need to use a parameter list and you can pass the WHERE condition in there to the module that has your cursor.
Hope this helps.
