Is it possible to print out an array in parts. For example you loop an array to check for 5 different things in an array. Can you subgroup the array with printing it. (eg. 1-5(sect1) 6-7(sect2)8-10(sect3)

what would I need to do: I know I can use a nested if to check, but I am having a problem printing the data in sub groups.
Tell me how anyone!

Can you show a little more of what you have now? The short answer is "yes", but it's not clear to me where you're having an issue. You just need 3 for loops (not nested).

this is the code I am working with. Now a college of mind did the same program and used 10 arrays. I think there is an easier way.
But I am getting trouble with getting it to work. Maybe I need to change my stategy abit

Program CarnivalBandSectiondata(INPUT,OUTPUT);
 {DECLARING OF ALL DATA TYPES}

VAR
FAmnt:array[1..13] OF REAL; {  declares cost array}
{MasName:array[1..13] OF STRING[30];declares name array}

Sn,Count :INTEGER; (*totnums*){declares the interger variables}
FAmnt,totAmt,SecCP1,SecCP2,totnums: Real; { declares the real variables}

(*Constants to declare the 5 cost for each section;*)
  Const
   {SecCP1=120;}
   {SecCP2=135;  }       {Change to your Cost}
  { SecCP3=185;  }
  { SecCP4=220; }
  { SecCP5=265; }

   NumOfMasmem = 2;       {number of Masqueraders in band}
 (*Names of masqueraders*)
   S1='BlueDevils';       {Change to your band names}
   S2='TriniRevellers';
  { S3='RedDragons';
   S4='OrangeSky';
   S5='IslandTribe'; }

Why not just do:

for i:= 1 to 5 do
begin
end;
for i:= 6 to 7 do
begin
end;
for i:= 8 to 10 do
begin
end;

Hmm!! That was a thought! I that case I would know that what I put in 1-5 and 6-8 would be different. But the case really was being able to pull out figures from the list of 1 - 10 and group them on the basis of difference of price in this case.
What are you thoughts with that happening then. I am forced to think go two dimensional arrays, but I do not want to do that just yet.

OK, I just reformatted your code so I can read it easier, and I think I see the trick. You don't need a 2d array, you need nested for loops. The outer loop would go through an array of bands, with the inner loop going through the array of prices and only printing them if it matches the parallel array for the band price.

Just a note: formatting matters. I'm posting the reformatted code here for reference.

Program CarnivalBandSectiondata(INPUT,OUTPUT);
 {DECLARING OF ALL DATA TYPES}

VAR
  FAmnt:array[1..13] OF REAL; {  declares cost array}
  {MasName:array[1..13] OF STRING[30];declares name array}

  FAmnt,totAmt,SecCP1,SecCP2,totnums: Real; { declares the real variables}

(*Constants to declare the 5 cost for each section;*)
Const
  {SecCP1=120;}
  {SecCP2=135;}       {Change to your Cost}
  {SecCP3=185;}
  {SecCP4=220;}
  {SecCP5=265;}
  NumOfMasmem = 2;       {number of Masqueraders in band}
  (*Names of masqueraders*)
