SCHAR in Paragraph 6.277 of the User's Manual

[Logman]

PROBLEM - Explanation is not correct.

Click on the HELP menu and then select IWBasic User's Guide.

In the User's Guide go to SEARCH and enter "SCHAR".

Double click on "SCHAR" in the Select Topic window. It will bring up the SCHAR Topic as follows:

=============================================================
SCHAR

Syntax
schar = SCHAR(exp)

Description
Converts a value to a single signed char.

Parameters
exp - A numeric or string expression

Return value
A single signed character or value

Remarks

Example usage

Code Select Expand


print SCHAR("testing")


SUGGESTION 1:
Parameters
exp - A numeric or string expression

should be changed to:
Parameters
exp - A numeric value in the range -128 to 127

This is because SCHAR will only accept numeric values and not string expressions as shown in the code example.

SUGGESTION 2:

Code Select Expand


print SCHAR["testing")


should be changed to:

Code Select Expand


schar i = SCHAR(50)
print i


This is because the code example does not work since SCHAR does not accept string expressions. In fact, you get an error message to that effect when you try running the code as it is shown right now.

What is really happening is that SCHAR(50), for example, returns an ASCII representation of the value 50, which is the ASCII character 2.

So, the following will give a new line when printed:

PRINT SCHAR(10)

Ten (10) is the ASCII representation of a line feed.
