perl(
SOURCE
)

The perl( function executes a perl program and returns the result (stdout).


Parameters

This function has one parameter:

source – Perl program (source code). Note: It is very convenient to use “pipe” delimiters for the source code parameter, for example |||code|||. This eliminates needing to worry about the delimiters appearing in the source code itself.


Description

This function executes Perl source code and returns the result. Here is a simple example.

perl({print "Hello World"."\n"."«timepattern(now(),"hh:mm:ss am/pm")»"}) ☞ Hello World
                                                                            4:47:26 PM

Panorama formulas can be embedded in the Perl source code using special tags. To embed a Panorama formula use

$«formula»$

The formulas are calculated in advance, then embedded into the source code as constants. For example, the formula $«2*3»$ will be embedded into the program as 6. The formula $«upper("hello world")»$ will be embedded as 'HELLO WORLD'. Note: You can embed database fields, global variables, fileglobal variables, and windowglobal variables into the formula, but local variables will not work. (You can, however, use local variables with the perl statement.)

In the case of text formulas any special characters will be encoded as necessary for a proper Perl constant. For example the formula $«{"}»$ will be embedded as '\x23'.

To embed a Panorama formula with no quotes or translation use

^«formula»^
