Perform and preform3/5/2023 ![]() ![]() Later versions of the program had some integration with Delrina's popular WinFax program, enabling users to fax material to clients based on information entered into PerForm. ![]() Some of the potential uses of the program included being able to create invoices, payment records, personnel and payroll forms, and just about any other standardized form that may have been required. Those entering information into the forms could not change or alter the forms they were limited to adding information in the various form fields on screen. The program consisted of two parts: a form design module which gave users a graphical user interface for creating and arranging form elements, using tools largely familiar to those using desktop publishing or paint programs of the era, and a separate form filling program which would display the resulting form that the user could then fill in. Chief Technical Officer Bert Amato and President of the company Mark Skapinker came up with the idea for the product while working as consultants that what their clients wanted was a way to fill in forms electronically, rather than an easier way to create paper-based forms from a computer. The initial version of PerForm was created in 1988 and was the first product released by Canadian software firm Delrina, which became best known for its later fax software program, WinFax. Later versions were designed to work in Windows 3.1, at which point it was succeeded by FormFlow. If identifier-1 is zero or a negative number at the time the PERFORM statement is initiated, control passes to the statement following the PERFORM statement.PerForm and PerForm PRO were electronic form programs, initially designed to work under GEM in DOS.Once he perform statement is initiated any changes to the id-1 will have no effect on the number of times the Para is to be executed.Two or more such active PERFORM must not have a common exit.When the performed procedures executes another PERFORM the procedures associated with the 2nd level PERFORM must be totally included in or totally excluded from the procedures of the first level PERFORM statement.The next programmer will appreciate not having to look all through the program to find the one or two lines of code in the paragraph you PERFORMed. If the number of lines in the routine is relatively small, use an in-line PERFORM instead of PERFORMing a separate paragraph.AFTER option to pass through all the entries in multiple dimensional tables. Use the WITH TEST AFTER option to force the code to be PERFORMed at least once.Make a main routine that PERFORMs other routines which in turn PERFORM other routines which themselves PERFORM other routines until the level of complexity of the PERFORMed routines is easily comprehended. Use the PERFORM statement to structure your code.Use the PERFORM statement to access code which needs to be executed from more than one location.PERFORM PARA-1 WITH TEST BEFORE VARYING WW-CNT1 PERFORM WITH TEST BEFORE VARYING WW-CNT1 FROM 1 The default condition is ' WITH TEST BEFORE, 'and it specifies that the condition is tested before the execution of statements in a paragraph. If neither the TEST BEFORE nor the TEST AFTER phrase is specified, the TEST BEFORE phrase is assumed. In either case, if the condition is true, control is transferred to the next executable statement following the end of the PERFORM statement.If the TEST AFTER phrase is specified, the statements to be performed are executed at least once before the condition is tested (corresponds to DO UNTIL). But this default is overridden by TEST AFTER phrase.Here the condition is tested before only at the beginning of each execution by default.Control is then passed to the next executable statement following the PERFORM statement. In the UNTIL phrase format, the procedure(s) referred to are performed until the condition specified by the UNTIL phrase is true.COBOL Inter-Programming Communication - CALLĪ block of statements or a paragraph/section will be executed in the PERFORM UNTIL statement until the specified condition becomes true.TSO-ISPF JCL COBOL VSAM DB2 CICS Tools Articles Job Portal Forum Quiz Interview Q&A
