# , reserved character

The , (comma) reserved character several
purposes:

- Separates subscript references within multidimensional arrays.

- Separates ac.exp, vc.exp, and sc.exp in dynamic array references.

- Delimits arguments within functions.

- Separates passed arguments in a call statement.

- When used with the crt or print statement, tabs to the next tab stop. Tab stops are established every 18 columnar positions.

- Line continuation for subroutine, call, common, dimension, equate and data statements.

## Syntax

```
dim.array.var(col.exp, row.exp)
dyn.array.var< ac.exp, vc.exp, sc.exp>
function(arg1, arg2,...)
call subroutine.name(arg1, arg2,...)
print str.exp, str.exp,...
```

## Example(s)

The comma delimits the row and
column arguments in a two-dimensional array reference.

```
if screen.array(13,12)...
```
The comma delimits the `ac.exp (17)` and
the `vc.exp (-1)` in a dynamic array reference.

```
customer.item<17,-1> = invoice.pointer
```
The comma delimits the arguments in the dcount() function.

```
cnt = dcount(string,char(253))
```
The comma separates the arguments in the list being passed
to the subroutine.

```
call display.lines(cust.item,balance,inv.list)
```
This prints `hello`, followed by 13 spaces
and `there`. This functions similar to a tab stop,
moving to the next multiple of 18 on the print or display line.

```
crt "hello" , "there"
```
