MATHO-PASCAL(1) Mathomatic Utilities MATHO-PASCAL(1)NAME
matho-pascal - display Pascal's triangle
SYNOPSIS
matho-pascal [number-of-lines]
DESCRIPTION
This command-line utility is optionally part of the mathomatic(1) package. It calculates up to 1000 lines of Pascal's triangle using
floating point arithmetic, dumping the lines to standard output. The default is to center one screen full.
Every number inside Pascal's triangle is the sum of the two numbers immediately above it.
Each line of Pascal's triangle is the same as the binomial coefficients for a given power.
The sum of all numbers in each line of Pascal's triangle is a power of 2.

PI(1) General Commands Manual PI(1)NAME
pi - Pascal interpreter code translator
SYNOPSIS
pi [ -blnpstuwz ] [ -i name ... ] name.p
DESCRIPTION
Pi translates the program in the file name.p leaving interpreter code in the file obj in the current directory. The interpreter code can
be executed using px. Pix performs the functions of pi and px for `load and go' Pascal.
The following flags are interpreted by pi; the associated options can also be controlled in comments within the program as described in the
Berkeley Pascal User's Manual.
-b Block buffer the file output.
-i Enable the listing for any specified procedures and functions and while processing any specified include files.
-l Make a program listing during translation.
-n Begin each listed include file on a new page with a banner line.
-p Suppress the post-mortem control flow backtrace if an error occurs; suppress statement limit counting.
-s Accept standard Pascal only; non-standard constructs cause warning diagnostics.
-t Suppress runtime tests of subrange variables and treat assert statements as comments.
-u Card image mode; only the first 72 characters of input lines are used.
-w Suppress warning diagnostics.
-z Allow execution profiling with pxp by generating statement counters, and arranging for the creation of the profile data file pmon.out
when the resulting object is executed.

For a basic explanation do
pi
In the diagnostic output of the translator, lines containing syntax errors are listed with a flag indicating the point of error. Diagnos-
tic messages indicate the action which the recovery mechanism took in order to be able to continue parsing. Some diagnostics indicate only
that the input is `malformed.' This occurs if the recovery can find no simple correction to make the input syntactically valid.
Semantic error diagnostics indicate a line in the source text near the point of error. Some errors evoke more than one diagnostic to help
pinpoint the error; the follow-up messages begin with an ellipsis `...'.
The first character of each error message indicates its class:
EFatal error; no code will be generated.
eNon-fatal error.
wWarning - a potential problem.
sNon-standard Pascal construct warning.
If a severe error occurs which inhibits further processing, the translator will give a diagnostic and then `QUIT'.

BUGS
Formal parameters which are procedures and functions are not supported.
The keyword packed and the function dispose are recognized but have no effect.
For clarity, semantic errors should be flagged at an appropriate place in the source text, and multiple instances of the `same' semantic
error should be summarized at the end of a procedure or function rather than evoking many diagnostics.
When include files are present, diagnostics relating to the last procedure in one file may appear after the beginning of the listing of the
next.
