Do you want a book? Or an online resource?
Are you actually wanting to learn how to leverage the language and write good, new code? Or have you have a library full of scripts dumped on you?
As fa as I'm concerned, Perl was written by a sadist! Yes, it works great, but any language where:
h*0?>)($%****>>%$#@!@
Is a valid line of code, and not a mistake my modem made, is a sadistic language! |

I have to agree with Ed. Perl is a good 4th or 5th computer language to learn, but heaven help the poor person learning it as their first computer language! I use Perl quite a bit, even though it is not as fast to code up as SAS, but I do NOT try to get fancy with Perl! For example, the default Perl variable name rules are (basically):
- variable names can be up to 255 characters
- variables are typed based on the first character -- $ for scalar, @ for array, % for hashes
- variables are defined upon first reference
- variable names are case sensitive (these two rules mean heaven help you if you're a bad typist)
- Perl automatically converts variables between numbers and strings as needed
I always make sure my Perl code has
which does help with some of the oddities that Perl can cause. |

Enrico apologies
I did google and found that site myself
Since I would be away from system I was looking for books
I am looking for a job change so why learning new things to me in hope to get a job
Frankly at this state of mind I dont know what is better |

Hi Pandora,
At the risk of overstepping bounds, i suggest you search for positions that need what you are already good at.
Learning new things is always to one's advantage. I would not consider something i was just learning to influence an interview.

To be frank I am good at Mainframes
Though oppurtunities are slim
So why I was trying out things outside of my skillset
Am not so experinced as experts but not regarded as a candidate to code that is the sad part |

I usualy install Perl on my usable PCs. Same with Rexx. But I use Rexx more often than Perl for writing stuff to run under windoze. |

I've used Regina more than OO. |

It depends on which interpreter is to the fore - i.e. I do not know as I basically use vanilla Rexx. |

no need with ooRexx to use the object garbage
You can write everything in classical rexx
with the advantage of being able to use if necessary the oorexx constructs
some of them are pretty powerful and not even too much OO |
