The Expression Builder also allows you to check the validity of an expression. If
there is a problem with the checked expression, the Expression Builder will identify a
specific error and a specific location in the expression and will display the error
statement in the Messages box. If the expression is valid and proper, the message
“Expression is valid” will be shown.
Intellisense
Intellisense is a common tool used in programming languages to auto-complete
expressions or lines of code quickly and efficiently.
Intellisense is being introduced in Arena Visual Designer for use with the @ROW
and @COL functions. The @ROW and @COL functions allow the user to define the
starting values for an array. Future releases will include other Arena Variable
functions; for example, NR, NC, TNOW.
Intellisense is triggered in the Scoreboard control when a user enters the @ symbol or
selects the Ctrl+Spacebar. Below is the information on the use of the @ROW and
@COL functions:
@ROW – function to define the beginning row value for an array
@COL – function to define the beginning column value for an array
Refer to the Intellisense online help for several example scenarios using this tool.
