Code Blocks (Cross Ref > OOP Basics)

By Mike Prestwood

ObjectPAL versus Perl: A side by side comparison between ObjectPAL and Perl.

Language Basics

Language basics is kind of a catch all for absolute beginner stuff. The items (common names) I chose for language basics is a bit random and include items like case sensitivity, commenting, declaring variables, etc.

Code Blocks

[Other Languages]

Languages Focus

The rules for code blocks within a language dictate where you can declare variables, how you "bracket" code, etc.

ObjectPAL: endXxxx

ObjectPAL code blocks are surrounded by statement ending keywords that all use End with camel caps such as endMethod, endVar, endIf, endSwitch, and endTry.

Syntax Example:

method

endMethod

var

endVar

if

endIf

switch

endSwitch

try

endTry

Perl:

In Perl, you create the entire HTML page within your .PL script file using print commands.

For Perl, PHP, JavaScript, Java,and C++, I prefer to put the first { at the end of the first line of the code block as in this example because I see morePeal codeformatted that way.

Syntax Example:

$x = "Yes";

If ($x == "Yes") {
  print "Hello world";

  print "I am a Perl coder.";
