COBOL Reference Modification With OF Syntax to use reference modification for a filed, which exists in multiple groups. Ex: 01 ww-grp1 03 name1 pic x(10) 03 sal pic 9(4) 01 ww-grp2 03 name1 pic x(10) 03 sal pic 9(4) name1 exists in both groups. So if we want to use reference modification for ww-grp1 move
Difference Between LINK XCTL and COBOL Calls(Static & Dynamic) 1. LINK –> Every time a subprogram is invoked an initialized version of working storage is provided. Dynamic& Static –> Not every time a separate copy of working storage is provided. It is provided only for the first time invocation of sub-program and for the subsequent
COBOL RANDOM Function generates the random fractional values ranging from 0 to 1. It generates values like 0.xxx For example if we declared the variable as below 01 WW-RANDOM-NUMBERS PIC 99.999 VALUE ZEROES. PERFORM VARYING WW-SUB1 FROM 1 BY 1 UNTIL WW-SUB1 > 9 COMPUTE WW-RANDOM-NUMBERS = FUNCTION RANDOM DISPLAY ‘–>’WW-RANDOM-NUMBERS END-PERFORM Result: –>00.443 –>00.060
