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-expression
evaluates to True (non-zero).
/BLINK[=Boolean-expression]
/NOBLINK (D)
Specifies that the displayed value blinks if Boolean-expression evaluates to True
(non-zero).
