cobol

What differences are there between the top level architectures of Cobol and Java? What are the styles and cultures that programmers adopt in these two languages? How can one best port from Cobol to Java? Didier DURAND I was the project leader for the project NACA mentionned above (automatic transcoding from cobol to java for 4 millions lines of Cobol). If you have any specific question, please feel free to get in touch with me via a comment at the bottom of my article mentioned above. We've had lots of projects around the world reusing our tools with good success. We still improve them on a

I am now working in mainframe, in some modules, to test Not null or Empty we see : NOT = SPACE OR LOW-VALUE The chief says that we should do : NOT = SPACE AND LOW-VALUE Which one is it ? Thanks! Chief is correct. COBOL is supposed to read something like natural language (this turns out to be just another bad joke). Lets play with the following variables and values: A = 1 B = 2 C = 3 An expression such as: IF A NOT EQUAL B THEN... Is fairly straight forward to understand. One is not equal to two so we will do whatever follows the THEN . However, IF A NOT EQUAL B AND A NOT EQUAL C THEN... Is a

I have been asked to write program to process 2 input files (customer and employee), matching the keys of both files and producing the following 3 output files : File-1: records that are on both files File-2: records that are on the customer file but not the employee file File-3: records that are on the employee file but not the customer file My loop is set so that it checks one record in customer file against every record in the employee file and then gets another key-pair value from the customer file and starts the process over. Currently: Matching Records - Must be in File1 and File2 (This

Say I have the following variable-length table defined in WORKING-STORAGE ... 01 SOAP-RECORD. 05 SOAP-INPUT PIC X(8) VALUE SPACES. 05 SOAP-STATUS PIC 9 VALUE ZERO. 05 SOAP-MESSAGE PIC X(50) VALUE SPACES. 05 SOAP-ITEMS OCCURS 0 TO 500 TIMES DEPENDING ON ITEM-COUNT INDEXED BY ITEM-X. 10 SI-SUB-ITEMS OCCURS 0 TO 100 TIMES DEPENDING ON SUB-COUNT INDEXED BY SUB-X. 15 SS-KEY PIC X(8) VALUE SPACES. 15 SS-AMOUNT PIC -9(7).99 VALUE ZEROS. 15 SS-DESCR PIC x(100) VALUE SPACES. When this program runs, will it initially allocate as much space as this table could possibly need, or is it more dynamic about

I am getting compilation error as, A "COPY" statement with "REPLACING" phrase was found within a nested "COPY". This is our compilation setting that we can not use REPLACING verb in nested copy. We have one copybook which is having multiple copy statements with replacing verb. Can anyone help me to resolve this error? Nesting COPYBOOKS in COBOL is a bit of a trick. In general you may nest copybooks only if they do not contain the REPLACING phrase and do not cause recursion. Suppose you had the following two copybooks: COPYBOOK ABC 01 :A:-VAR-A1 PIC X. 01 :A:-VAR-A2 PIC X. COPY XYZ REPLACING ==

In my university, we're being taught COBOL, and I'm trying to get a head start and learn COBOL, C++, and Java before I get into the classes next year. Problem is; COBOL is so old, it's hard to grab support for it in mac (my laptop is a mac). I understand it runs fine on Mac, but finding someone who can explain how to set up the compiler is another story. You can use brew to install GNU Cobol (Open Cobol). Just type: brew install gnu-cobol Then to compile program use: cobc -x hello.cob Browse --help for more option (like super nice -free ) Is there a particular Cobol you are trying to use. If
