What are the features of pascal programming language?

There are many features that can be considered, and to go through all of them is a big undertaking.

What I however consider the most important is its logical buildup.

It's most logical way of working mean that the threshold for learning and using it is very low.

Anybody can have a look at source code, and start writing Pascal Software.

It is a compiling language also. The source code makes assembler code when compiled. This provides for the highest speed during execution.
