The Native Mode Library consists of two products designed to increase the speed and performance of the System. They are the Native mode library for number rounding, and ImageXpress for data extraction. Native Mode Library Specifications
Before computations are performed, real numbers in the Manman system are usually rounded to two decimal positions. To do so, the system calls compatibility mode HP routines known as EXTIN and INEXT to convert each real number to an ascii string, truncate the insignificant decimals, and reconvert the ascii string back into a real number. In a normal report, thousands of these will degrade the performance of the system. The Native Mode Library uses native mode routines to perform exactly the same function. This yields substantial improvements in Manman reports and utilities that total numbers.
ImageXpress Detail Specifications ImageXpress is a fast data base extract and sort routine that runs with existing programs without source code changes. ImageXpress intercepts serial DBGET calls and replaces them with high speed MR NOBUF serial reads of the data set. ImageXpress can be used to improve the speed of Quiz, UDMS, and DataExpress.
