npc - new icl pascal compiler (front-end) [ options ] file  is  a
program  analyser  that checks the syntax and static semantics of
programs written in ICL Pascal. To run type

            npc filename

where contains the program source text. Note that the  file  name
must  end  in a .pas suffix. Further control over is exercised by
the following options.  Control the generation of a listing file.
is a key-word chosen from 'short', 'normal', or 'full'. The first
lists only those lines in error, the second lists the source text
together with errors, and the third lists both primary and secon-
dary source text together with errors. If the key-word is  ommit-
ted,  'normal'  is selected by default. In each case, the listing
file is written to standard output.  Control the  langauge  level
against  which  checking  is performed.  is a single digit in the
range 0 to 2. The effect of each setting is as follows.

s        Level

0        ISO Level 0 (no conformant arrays)
1        ISO Level 1 (conformant arrays)
2        ICL Pascal  (Level 1 + ICL extensions)

Control the recognition of embedded directives. is a three  char-
acter  string  which must prefix each directive. If string is om-
mitted, no directives are  recognised.  By  default,  is  set  to
'***'.   The   following   list   of  directives  is  recognised.
READ(file) npc takes input from the secondary  source  file.  The
effect  is  identical  to  the pre- processor directive #include.
Secondary source text will be listed if  the  -Lfull  option  has
been specified.  PAGE causes a new page to be output to the list-
ing file. The directive is only  effective  if  the  -Lnormal  or
-Lfull options have been specified.  LINES(n) Eject n blank lines
onto the listing file.  If there  is  insufficient  room  on  the
current page of output, a new page is ejected instead. The direc-
tive is only effective if the -Lnormal  or  -Lfull  options  have
been  specified.  LIST(SHORTLIST) has the same effect as -Lshort.
LIST(LIST) has the same effect as -Lnormal.  Control the contents
of  the  listing  file  sub-heading.  is the text of the new sub-
heading enclosed in double-quote marks. If exceeds 24 characters,
then it will be truncated.  For example,

      npc -L -h "new product" product.pas >listing

causes the program in product.pas to be checked. A  listing  con-
taining  errors  and source lines is written to the file listing.
Each page of the listing will contain a heading that includes the
string "new product".
