Formatting panel definition statements

This topic describes panel definition statements:

Assignment statements. See The assignment statement.
Note: You can use ten built-in functions in an assignment statement:
- TRUNC (truncate)
- TRANS (translate)
- PFK (function key)
- LENGTH (return length of variable)
- UPPER (return uppercase value of variable)
- LVLINE (last visible line)
- ADDSOSI (add shift-out character)
- DELSOSI (delete shift-out character)
- ONEBYTE (convert to a 1-byte code)
- TWOBYTE (convert to a 2-byte code)

These types of data references can appear within panel section statements:

Dialog variable

A name preceded by an ampersand (&)

Control variable

A name preceded by a period (.)

Literal value

A character string not beginning with an ampersand or period. A literal value can be enclosed in single quotes (‘’). It must be enclosed in single quotes if it begins with a single ampersand or a period, or if it contains any of these special characters:

Blank < ( + | ) ; ¬ - , > : =

A literal can contain substitutable variables, consisting of a dialog variable name preceded by an ampersand (&). The name and ampersand are replaced with the value of the variable before processing the statement. Trailing blanks are removed from the variable before the replacement. You can use a double ampersand to specify a literal character string starting with, or containing, an ampersand.

In the description of statements and built-in functions that follows, a variable can be either a dialog variable or a control variable. A value can be either type of variable or a literal value.
