The last 2 bytes of data-name-2 contain the VSAM feedback code again in binary. The code value is 0 through to 255. The Function Code and Feedback Code are set only if the Return Code is set to non-zero. If they are set when the Return Code is zero, the contents of the fields...
COBOL is also not applicable here, save as a way to make this effort that much harder, given the added glue code needed around calling system services from that language. You'll need to query the terminal directly. In short, you'll send a sequence such as a DSR directly,...
A read-only transaction does not acquire any additional data locks to provide transaction-level read consistency. The multi-version consistency model used for statement-level read consistency is used to provide transaction-level read consistency; all queries return information with respect to the system...
A field guide that also covers why we need to rethink our expectations, and what software engineering really is. A guest post by software engineer and engineering leader Addy Osmani
TechTricky is a technology blog to help web developers to give tips and code examples on html, css, jquery, web applications and software tools.
mutex return count } Comparing and Testing Now, let's write a simple test to ensure that our code is correct, concurrent safe, and does not have data races. We will also write some benchmarks and compare the performance of different approaches. package callcounter_test import ( "call...
Just as there are still billions of lines of CoBOL code in use today that need to be maintained, support for a legacy standard such as CSV is likely to be required long after it has stopped being implemented in new designs. [top] The CSV File Format Each record is one line ......
5) CLOB columns will be a fixed length equal to the longest CLOB expression in the table. 6) CLOB columns with NULL values depend upon this tiny user-defined function: Code: create or replace function null_clob return clob is begin return ' '; end / 7) The widths of the fixed-lengt...
If we have managed to successfully open an ACM codec, we now need to set up an instance of ACMSTREAMHEADER which contains points to both an input and an output buffer for your codec. These are passed in as pointers, and they should be pinned so that the garbage collector does not move...
2. Example of How to Change from Conventional Code to the Invariant One Let us clear this statement on some examples. However, let's begin with considering a couple of auxiliary functions that we will repeatedly use later: int sign( double v ) { if( v < 0 ) return( -1 ); return(...
