A programming language initially developed for teaching programming by Niklaus Wirth at ETH Zürich.
Pascal is a procedural language, similar to C.
Descendents include: Delphi, Modula 2, Oberon. See http://www.xploiter.com/mirrors/pascal/default.htm for a self paced learning module on pascal programming.
The language was named in honor to the French philosopher and mathematician Blaise Pascal, who is also known for the Pascal Triangle. Here's Tcl code that produces the next row, given one row:
proc pascal {{lastrow 1}} {
set res 1
foreach a [lrange $lastrow 1 end] b $lastrow {
lappend res [expr $a+$b]
}
set res
} ;# RS

% pascal {1 1}

% pascal {1 2 1}
1 3 3 1
% pascal {1 3 3 1}
