PROCEDURES:Fully recursive procedures are supported. Value or variable parameters are supported.
predefined procedures: HALT PAGE POKE READLN RESET READ
WRITELN WRITE WRITEHEX LINE(COL,X1,Y1,X2,Y2) {to draw a line from X1,Y1 to X2,Y2} USER GRAPH
STATEMENTS:BEGIN – END
IF – THEN – ELSE
CASE – OF – ELSE/END
WHILE – DO
REPEAT – UNTIL
FOR – TO/DOWNTO – DO
OTHER:This implementation comes with its own integral editor, which allows a program to be written and saved to tape. It allows the table of standard predefined functions and procedures to be extended readily and simply. It is well documented. It supports the block graphics of the NASCOM 2, or N1 with Econographics.
ACCURACY:Six to seven significant figures.


4. Polydata Blue Label Pascal

This implementation may also be available from some of the Nascom dealers in this country, but I have not been able to obtain confirmation of this report.

DATA TYPES:REAL 11.5 significant digits (!!!), 1E-38 to 1E38
INTEGER 16 bits, –32768 to 32767
STRING Up to 255 characters
BOOLEAN Logical variables
ARRAY..OF with multiple dimensions
OPERATORS:+ – * / DIV MOD SHIFT AND OR EXOR = <> < > <= >=
FUNCTIONS:ABS SQR SQRT SIN COS ARCTAN LN EXP INT FRAC SUCC PRED ODD TRUNC ROUND ORD CHR LENGTH MID LEFT RIGHT CONCAT ADDR RANDOM POINT KEYBOARD
PROCEDURES:WRITE WRITELN READ READLN LOAD SAVE CALL SCREEN PLOT
STATEMENTS:BEGIN – END
FOR – TO/DOWNTO – DBO
REPEAT – UNTIL GOTO
IF – THEN – ELSE
WHILE – DO
CASE – OF – OTHERS
INIT – TO
OTHERS:The specification of the editor supplied looks impressive, supporting a window on the text, to allow 80 char lines to be handled with ease. It supports 27 editor commands. User written machine code subroutines are supported using procedures/functions declared as EXTERNAL.
ACCURACY:11.5 digit accuracy claimed.
