A typical job script will contain multiple job steps executed in a predefined sequence. Using Kolmogorov complexity to measure difficulty of problems? If you are using a COBOL program, just move the packed decimal variable into a numeric field and then try to write to output file. The fewer decimal positions of the result field will be rounded because of the ROUNDED keyword on the ADD statement. How to convert a alphanumeric string into numeric decimal in COBOL I am unsure how to interpret the decimal place and sign. This video shows the format in which numeric data is stored in Zoned decimal (conventional) and packed decimal (COMP-3) format. REFFILE. The lower nibble of the last byte has 13 if the number is negative, and something else, (usually 12) if positive.
