DISPLAY SYMBOLIC

DISPLAY SYMBOLIC

Display a text in a monitor picture depending on the result of an expression evaluation.

Format

DISPLAY SYMBOLIC expression "text-string" [,"text-string"]...

Command Qualifiers	Defaults
/BELL=Boolean-expression	/NOBELL
/BLANK=Boolean-expression	/NOBLANK
/BLINK=Boolean-expression	/NOBLINK
/BOLD=Boolean-expression	/BOLD
/REVERSE	/NOREVERSE
/UNDERLINE=Boolean-expression	/NOUNDERLINE
/X=column	Column of previous item
/Y=row	Next free row

Description

The DISPLAY SYMBOLIC command displays one of the text strings depending on the value of expression. The first string is output if the expression's value is zero (0), the second string is output if the expression's value is 1, and so on. If the expression has a value for which there is no corresponding entry in the list of texts, then the value itself is printed. (Note that there is a limit of 255 characters on the size of one command to RTR, so large numbers of long strings should be avoided.)

The command can be used within a monitor file or issued at the RTR prompt when interactively defining a monitor picture for use in a subsequent MONITOR command.

Parameters

expression

The expression to be evaluated. Expression can either be the name of a single data item, or an expression combining several data items using simple arithmetic operations and constants. In the latter case, the data items must all be of the same type and EXPRESSION must be enclosed in quotation marks.

Qualifiers

/BLANK[=Boolean-expression] /NOBLANK (D)

Specifies that the displayed value is replaced by blanks if Boolean-expressionevaluates to True (non-zero).

/BLINK[=Boolean-expression] /NOBLINK (D)

Specifies that the displayed value blinks if Boolean-expressionevaluates to True (non-zero).
