Designing the Forms FORM21 and FORM22 must be designed with SIGEDITOR. The final step when using SIGEDITOR is to generate the input/output specifications for the forms file containing the forms from the utilities menu (see chapter 3 for more details). Once this process is complete, you can begin constructing the RPG program. FORM21 For this example, begin with FORM21 by setting the correct form attributes. Enable command keys 1, 2, 3, and 7 (A, B, C, and G) by placing a character in the space identified by the correct letter. The keys correspond to the three options available to the user (adding, deleting, or updating). Command key 7 is used to exit the program. Indicator 60 is used for override fields. The visual design of FORM21 is achieved by typing screen constants (labels or directions) and creating three fields for the social security number, as shown in Figure 4-2. These fields are designated as numeric input fields and do not have to be output fields because they are only used to read the social security number. The three fields are inverse video fields. The RPG program reads these three fields as one. Create a fourth field under the social security number fields to display any error messages. This is an output field conditioned by indicator 60 with the blink field attribute turned on. The field is only used to display a message to the user, not to return data to your program. The inverse video attribute is turned off, and the length of the field is the length of the message that is displayed. The message identification numbers are given in the program as constant values. The form title field on the first line is also a message type field; this one has the message identification (000301) coded on the form instead of the RPG program. A fifth field, placed in the upper left corner of the form, is one character long. This field is a protected field of constant type, with its contents hidden from the user by the security video attribute. This field is specified as both input and output. The constant 1 is stored in the field and is used to identify the data from this form by the RPG program. FORM22 The form attributes for FORM22 do not have to be changed because the form uses all default values. The social security number fields are output fields, because they are used to display information only and not to return the information to your program. The inverse video attribute for these fields is off. The NAME, ADDRESS, ZIP CODE, and PHONE NO. fields are input and output fields. These fields can return data to your program after an add or an update operation, or can display data to the screen for the user to modify. All fields are inverse video fields. The NAME and ADDRESS fields are specified as alphanumeric, and the ZIP CODE and PHONE NO. fields are numeric. The NAME, ADDRESS, and ZIP CODE fields are also specified as no-adjust and no-fill by leaving the adjust fill attribute blank; this causes the data in those fields to be left-justified. FORM22 also has a one-character protected field of constant type in the upper left corner. The security video attribute is turned on. This field is both input and output and stores the value 2. The field is also used to identify data from this form by the RPG program.
