Then rewrite records in FILE A to change all “A” in the File to “B”. I am a very basic Cobol programmer - openfile/read rec/write rec/close file What I need to understand is how to do the following I want to either pass a parm or a DD statement that contains a GDG Base //S1 EXEC PGM=X,PARM='GDGBASE' Or //S1 EXEC PGM=X //GDGBASE DD DISP=SHR,DSN=gdgbase,GDGORDER=LIFO Read the GDG backwards code for program to create a attendence report of employees in cobol identification division. read cust-order-file at end move 'no' to are-there-more-records. Show me some sample program. ... Write Sequential File. When using COBOL, you can open data files in one program, and perform file operations (such as READ and WRITE) in another, as long as all the programs are in the same run unit. The source program is in member XMPLE1 of source file QLBLSRC in library MYLIB. Format 2: ... may or may not be equal to the number of character positions defined by the logical description of that record in the program. The COBOL program is written using COBOL/2 dialect but also works with COBOL for MVS and COBOL/370. 05 TEMP-DATA. one for each type. COBOL will prep an empty file for first write if ... *> Open optional index file for read write open i-o indexing *> populate a sample database move "1234567800a01some 12345678 data here" to ... end-display read indexing next record at end set no-more-records to true end-read . An appropriate FD for this file could be written as: FD TEMP-FILE. select emp-out-file assign to … My program creates and writes the file just as if it was an indexed file, but AcuXML writes it out as XML behind the scenes. Below is the sample Batch COBOL program that reads a flat input file and generates an output file. These functions have been replaced by the Registry functions in 32-bit programs (see COBREG sample) but still exist to main- tain compatibility with 16-bit programs. IDENTIFICATION DIVISION. OPEN To connect the VSAM data set to your COBOL program for processing. You can make writing a file take 100 lines of code in cobol so I tried to keep it as tight as I know how.
