i have problem to finish some functions in this code
program lab4;
var inFile : text;
var pArray : array[1..10]of real; //array of 10 integer values containing patterns to search in a given set of numbers
var rArray : array[1..10]of integer; //array containing result of pattern search, each index in rArray coresponds to number of occurences of
//pattern from pArray in sArray.
var sArray : array[1..100] of real; //array containing data read from file
var accuracy : real;
(****************************************************************************)
function errMsg:integer;
begin
if ParamCount < 3 then
begin
writeln('Too few arguments');
writeln('Usage: ./lab4 lab4.txt <accuracy> <pattern_1> <pattern_2> <pattern_n>');
errMsg:=-1;
end
else if ParamCount > 12 then
begin
writeln('Too many arguments');
writeln('Maximum number of patterns is 10');
errMsg:=-1;
end
else
begin
assign(inFile,ParamStr(1));
{$I-}
reset(inFile);
if ioresult<>0 then
begin
writeln('Cannot open ',ParamStr(1));
errMsg:=-1;
end
else
errMsg:=0;
end;
end;
(****************************************************************************)
procedure readPattern;
var errPos,idx:integer;
begin
if errMsg=0 then
begin
for idx:=1 to ParamCount-2 do
begin
Val(ParamStr(idx+2),pArray[idx],errPos);
writeln('pArray:',pArray[idx]:2:2);
end;
end;
end;
(****************************************************************************)
procedure getAccuracy; //Function should get the accuracy as the first param (after the program name)
begin
(here where i stopped : (( )
end;
(****************************************************************************)
function readSet:integer; //Function returns number of elements read from file
var idx,errPos:integer;
var sChar: string;

if errMsg=0 then

idx:=1;
repeat
begin
readln(inFile,sChar);
VAL(sChar,sArray[idx],errPos);
writeln('sArray:',sArray[idx]:2:2);
idx:=idx+1;
end
until eof(inFile)=TRUE;
end;
readSet:=idx-1;
end;
(****************************************************************************)
procedure searchPattern(sNumber:integer); //Function should search and count pattern(patterns) occurence in a given set
what the best solution for this part??
(****************************************************************************)
procedure dispResult; //Function should display the result of pattern(patterns) search
