ROWSIZE

ROWSIZE

This function will return the number of rows in an array.
Format
ROWSIZE(A)
ROWSIZE(A$)
Parameters
A = integer array to query for the number of rows.
A$ = string array to query for the number of rows.
Returns
Returns a 0 if the variable is not an array. Returns the number of elements in the array if the array has only one dimension. Returns the size of the first dimension if the array has two dimensions.
Example
This example shows how to determine the number of elements in a one dimensional string array. 
10 DECLARE STRING NAMES$(3) 
20 LET NAMES$(1) = "Fred" 
30 LET NAMES$(2) = "Wilma" 
40 LET NAMES$(3) = "Barney" 
50 REDIM NAMES$(4) ! Make room for Betty 
60 LET NAMES$(4) = "Betty" 
70 LET NUMOFNAMES = ROWSIZE(NAMES$) 
80 PRINT NUMOFNAMES
Example
This example shows how to determine the number of rows in a two dimensional numeric array. 
10 DECLARE NUMERIC SQROFTWOLOOKUP(3,2) 
20 LET SQROFTWOLOOKUP (1,1) = 1 
30 LET SQROFTWOLOOKUP (1,2) = 2 
40 LET SQROFTWOLOOKUP (2,1) = 2 
50 LET SQROFTWOLOOKUP (2,2) = 4 
60 LET SQROFTWOLOOKUP (3,1) = 3 
70 LET SQROFTWOLOOKUP (3,2) = 8 
80 LET NUMOFSQRS = ROWSIZE(SQROFTWOLOOKUP) 
90 PRINT NUMOFSQRS
