Explain call by context by comparing it to other calls. Ans: The parameters passed in a call by context are protected from modification by the called program. In a normal call they are able to be modified. 36. What is the difference between comp and comp-3 usage? Explain other COBOL usages. Comp is a binary usage, while comp-3 indicates packed decimal. The other common usages are binary and display. Display is the default. Comp is defined as the fastest/preferred numeric data type for the machine it runs on. IBM Mainframes are typically binary and AS400’s are packed.’ 37. I understand the possible causes for S0C1 & S0C4 abends, but what are they really? Ans: A S0C1 occurs if the CPU attempts to execute binary code that isn’t a valid machine instruction; e.g. if you attempt to execute data. A S0C4 is a memory protection violation. This o
