	You'd prefer REBOL, perhaps? 

	REXX at least has some structure to it <G>

	NB: Pascal has, like Ada, always been a <cap><lowercase> name -- not
like the origins of COBOL, FORTRAN, BASIC, et al.

	Very early? The common versions were probably UCSD (running on UCSD
P-System); or a port of the P-4 compiler (which had been published in book
form) -- maybe a "tinyPascal" (integer only I suspect). Radio Shack did
provide Alcor Pascal for the TRS-80.

	Later, you might have encountered TurboPascal -- which bore little
resemblance to a Jensen&Wirth Pascal. 

	J&W was one-program<>one-file (no link libraries, no "include" files as
I recall); very limited math functions if one is trying for scientific
applications (sin, cos, arctan were the trig functions I recall), and that
very unfriendly I/O system (console I/O required special handling from file
I/O as Pascal does a one-element pre-read when an I/O channel is opened --
which occurs on program load for stdin, much before a program could output
a prompt to the user).

	Even my first exposure to VAX/VMS Pascal, which did allow for separate
compilation and linking, required me to declare interfaces to the FORTRAN
run-time library to get advanced math functions (I believe later versions
incorporated the FORTRAN math natively).
