Estimating Field-Attribute Entries

Although the actual number of field-attribute entries a screen definition contains

depends on the layout of the screen, you can estimate the number of field-attribute

entries by multiplying the number of screen fields by 2. For example, a screen with 10

input fields has approximately 20 field-attribute entries. The number of field-attribute

entries is twice the number of screen fields because the terminal also identifies the

spaces between the screen fields as fields.

Assessing Terminal Capacity

“Terminal capacity” refers to the number of field-attribute entries that a terminal can

store given a specific DISPLAY-PAGES setting. The following tables list the average

number of field-attribute entries that individual terminals can store for each value of

DISPLAY-PAGES.

Table F-1 lists the average number of field-attribute entries a 6520 terminal can store.

Note that the number of pages that a 6520 terminal can cache is fixed at 3.

Table F-2 lists the average number of field-attribute entries a 6526 terminal can store.

Table F-3 on page F-4 lists the average number of field-attribute entries a 6530

terminal can store.
