chr(<value>) chr(<value1>[, <valueN>]) chr$(<value>) chr$(<value1>[, <valueN>])
Returns a string containing the ASCII characters whose codes are the given values. The arguments must be a numeric expression and, unlike Sinclair BASIC, parenthesis are mandatory. Returned value type is string.
REM Char for ASCII code 65 is 'A' PRINT "CHR(65) is "; CHR(65)
This function is extended, and several values can be given at once. The result is a concatenation of all the given values:
REM Chars for ASCII codes from 65 to 67 ('A' to 'C') PRINT "CHR(65, 66, 67) is "; CHR(65, 66, 67)
The following lines are both equivalent, but the 2nd is faster and takes less memory:
REM These two sentences are equivalent PRINT "CHR(65, 66, 67) is "; CHR(65) + CHR(66) + CHR(67) PRINT "CHR(65, 66, 67) is "; CHR(65, 66, 67)
In fact, if the compiler detects the programmer is using
CHR(x) + CHR(y), it might compile it as
CHR(x, y) to perform such optimization.
- This function is 100% Sinclair BASIC Compatible, but parenthesis are mandatory
- This function is expanded comparing to the original Sinclair BASIC
- As with other functions and variables, the trailing
$can be omitted.
