At run-time, compiles and runs each element in a text expression as a formula. Returns the result of the last formula expression in the list or an error if an error is generated by any of the formula expressions in the list.

Note This @function is new with Release 6.

Syntax

@Eval(textExpressions)

Parameters

textExpressions

Any text expressions that you want @Eval to evaluate. Surround the text expression to be evaluated with quotation marks (" ") and escape the quotes around individual text expressions within the formula with back-slashes (\). Use the plus sign (+) to concatenate text expressions.

lastExpression

The value of the last expression.

This function is useful in agents, hotspot buttons, and toolbar buttons and when you want to evaluate multiple text expressions at run-time from within a single @function.

Use of @Eval in view columns and selection formulas may produce unexpected results. Because this function is evaluated at run-time, the view engine is unable to follow its standard procedure of analyzing the formulas ahead of time to discover what types of @functions it will encounter and prepare for them.
