, 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"
