Arguments. The JSON string is declared in memory, as are the results from the parse, and everything is printed out for clarity. Delimited specifies the end of string. FINIT(), FINIT32() - initialize fielded buffer. Advertisements. COBOL - String Statement The STRING statement strings together the partial or complete contents of two or more data items or literals into one single data item. String(Starting-Position:Length) MOVE '18' TO AGE-OUT(1:2) does the same as what we did with STRING command. However, it has been found that there is another serious consequence by omitting <length> if <field> is a large area. COBOL were long variable names, English words for commands and the separation of data descriptions and instructions. MOVE statement copies the value of a variable to another variable. Perform Times. 23) What are all the divisions of a COBOL program? However, you can use the LENGTH OF special register in a greater variety of contexts. FML-LENGTH IN FML-REC is the length of the record. DB2 date functions are the scalar functions provided by IBM to handle and manipulate the date values in the DB2 database. Arguments.
