Ineed help

GHost182

I am currently doing my School Based Assesment (SBA) and I have created an
array of records. In order to complete the assignment, I need to be able to edit these records. Everywhere else that I checked is useless. Can you help me? Here is a sample of the code if that might help(Turbo Pascal). I also cannot get sorting to work.

program librarything (input, output);
uses {win}crt;
type
memrec= record
fname:string;
lname:string;
other:string;
homeaddress:string;
form:string;
tel:char;
parent:string;
partel:char;
powork:string;
end;
brec= record
fname:string;
lname:string;
bkname:string;
duedate:string;
nowdate:string;
end;
memarray= packed array[1..20] of memrec;
memrecfile= file of memrec;
borarray= packed array[1..20] of brec;
brecfile= file of brec;
var
memray:memarray;
rtemp:memrecfile;
btemp:brecfile;
reginfo:memrec;
regfile:memrecfile;
binfo:brec;
bfile:brecfile;
size:integer;

{*************************************************************************************************}
PROCEDURE SortArray(var memray:memarray; var regfile:memrecfile);
VAR
location,index,size:INTEGER;
current:memrec;
BEGIN
reset (regfile);
size:=1;
WHILE NOT EOF (regfile) DO
BEGIN
read(regfile,memray[size]);
size:=size+1;
END;
reset (regfile);



FOR index:= 2 TO size-1 DO
BEGIN
current:=memray[index];
location:=index;
WHILE (location > 1) AND (memray[location-1].fname < current.fname) DO
BEGIN
memray[location]:=memray[location-1];
location:=location-1;
END;
memray[location]:=current;
END;

rewrite(regfile);
FOR index:= 1 TO size-1 DO
BEGIN
write(regfile,memray[index]);
END;
reset(regfile);

END;

{*************************************************************************************************}

begin{main}
assign(regfile,'F:I.T. SbaPascal
egisternew');
assign(bfile,'F:I.T. SbaPascalorrow');
assign(rtemp,'F:I.T. SbaPascal
temp');
assign(btemp,'F:I.T. SbaPascaltemp');
{rewrite(regfile);
rewrite(rtemp);}
SortArray(memray,regfile);
end.
