Parameters

text-expression: The TEXT expression whose bytes are to be counted.

Examples

OLADM1799 Example 8-42 Counting the Bytes in the Longest Name

You would like to know the length of the names of your products so you can specify the appropriate width for the label column in a report. You can use the NUMBYTES function in combination with the LARGEST function to find the length of the longest label. Then use that value to set the column size. The following statements in a program find the longest name and use the byte count to format a report.

firstcol = LARGEST(NUMBYTES(name.product))+1
LIMIT month TO FIRST 3
FOR product
   DO
     ROW WIDTH FIRSTCOL name.product WIDTH 6 ACROSS month - 
     FIRST 3: units
   DOEND

When the program is run, it produces the following output.

3-Person Tents      200    203    269
Aluminum Canoes     347    400    482
