JCL is the "Job Control Language" for IBM Mainframes. It has statements like "//CTRLTABL DD DISP=SHR,DSN=SYS1.FOCUS.MSO.MSOPROF(CTRLTABL)"

I was advised by someone that the way to write JCL was to find someone else who had managed to do the same thing and copy it. And they were serious.

The entry in "shoot in the foot" for JCL is: "You shoot yourself in the head just thinking about it."

This should be the one for Perl:

You write the algorithm to shoot yourself in the foot.  A week later, when you go to run it, you realize there is a bug.  Looking at the source code, you have no idea what it actually does anymore.

(Perl is often called a 'Write-only' language)

What a great list!

I like Postscript: "foot bullets 6 locate loadgun aim gun shoot showpage"
And Java: "You locate the Gun class, but discover that the Bullet class is abstract, so you extend it and write ... and call the doShoot method on the instance of the Gun class ... and the instance of Bullet is passed to the Foot. But this causes an IllegalHitByBullet exception to be thrown, and you die."

Stumbling, of course, because you shot yourself in the foot

Mastering? I wish!

More like stumbling around in the dark looking for the light switch. Eventually the light goes. smile

Programme mastering, hmmm...

Just persistence. smile

I use the standard latex that comes with linux, so the only creative thing I have done is to integrate it with the forum.

So when you type some latex, my software grabs the text, puts it into a file with some other standard commands, runs the latex command on the server, takes the results and then has to reformat them for the forum, then copies them to the right location and hey presto you see the image!

More testing:



Works really well for lining up the equals sign too.
