PROGRAM attribute
The PROGRAM attribute can specify an external
application program to edit TEXT or BYTE fields.
Syntax
PROGRAM = "editor"- editor is the name of the program that must be used to edit the special field data.
Usage
You can assign the PROGRAM attribute
to a TEXT or BYTE field
to call an external program to work with the BYTE or TEXT values.
This attribute works in TUI mode only.
Users can invoke the external program by pressing the exclamation point ( ! ) key while the screen cursor is in the field.
The external
program then takes over control of the screen. When the user
exits from the external program, the form is redisplayed with any
display attributes besides PROGRAM in effect.
When no PROGRAM attribute is used, the DBEDIT environment
variable defines the default editor.
