Hi, I’am not a cobol programmer. For a work I need to read vision files because I need to integrate two different systems. I can read it correctly using vutil -unload and parsing the fixed record structure file it will give me in output.
As the file is very big, this process requires time to read and parse the entire vision file every time. I found the extract option of vutil with which I can specify a key value to start with. However I cannot understand how I can specify this value when the primary key of the vision file has multiple parts.
