CHR
Syntax:
CHR(expr)
CHR(string,position)
Where: expr = number from 0 to 255
string = string variable
position = 1 to length of string
Function:
Converts expr to ASCII character or prints string at position
Mode:
Command, run
Use:
PRINT CHR(65)
PRINT CHR($(0),1)
DESCRIPTION
CHR is a dual use operator, similar to ASC. One version converts a numeric expression to an ASCII
character, allowing a variety of string manipulation operations. The second version uses CHR to print
individual characters in an ASCII string. expr is a decimal number and truncates numbers from 0 through
65535. There must be no space between CHR and the left parentheses or an ARRAY SIZE error results.
Although expr can be any integer, printable ASCII characters range from 20H through 7EH (32 through 127).
