PERFORM Statement Simple form of PERFORM acts very similar to GO TO statement, except that after execution of paragraph control will return back to the next statement of PERFORM statement. Format - 1 PERFORM procedure-name-1 Example 1 - Below picture represents the difference between GO TO and PERFORM statements.
COBOL - Conditional Statements - Conditional statements are used to change the execution flow depending on certain conditions specified by the programmer. Conditional statements will always eva.
However, Compaq COBOL also lets your program control logical page advancement with the WRITE statement. To manually advance to the next logical page from any line in the current page body and position the printer on the first print line of the next page body, your program must include the WRITE statement with either the BEFORE ADVANCING PAGE clause or the AFTER ADVANCING PAGE clause.
BEFORE, ADVANCING, LINES, PAGE can be used in combination. Can also specify the source record WRITE Output-Buffer FROM Output-Detail BEFORE ADVANCING n LINES. Examples: WRITE Output-Rec AFTER ADVANCING PAGE. WRITE Output-Rec BEFORE PAGE. WRITE Output-Rec FROM Output-Detail AFTER ADVANCING 2 LINES. WRITE Output-Rec BEFORE 2.
A single execution of a SEND statement represented by Format 1 releases only a single portion of a message segment or a single portion of a message to the MCS.A single execution of a SEND statement represented by Format 2 never releases to the MCS more than a single message or a single message segment as indicated by the content of the data item referenced by identifier-2 or by the specified.

NAMEOPTIONS The NAMEOPTIONS option specifies whether the name you pass to the OPEN statement can contain File Handler options.
Control is transferred to the end of the READ statement or to imperative-statement-2, if specified, in the NOT AT END phrase.In the latter case, execution continues according to the rules for each statement specified in imperative-statement-2.If a procedure branching or conditional statement that causes explicit transfer of control is executed, control is transferred in accordance with the.
AFTER ADVANCING 1 LINE' when ever a simple WRITE statement is encountered (no ADVANCING clause). This fix should conform to the COBOL tradition for a 'PRINTER' file, and generate the expected output. Re: (Tiny-cobol-users) about my proposal of change in our webpages.
