CHARACTER (LET)

CHARACTER

Let Subcommand

Convert a parameter or a variable to a string based on the ASCII collating sequence.

Most modern computer platforms use the ASCII collating sequence to code characters. In the ASCII collating sequence, the integers 0 to 255 are used to represent specific characters. Specifically
1. 48 - 57 denote the digits 0 to 9
2. 65 - 90 denote the upper case characters A to Z
3. 97 - 122 denote the lower case characters a to z

The other values represent special characters such as quotes and ampersands or non-printing characters such as tabs, carriage returns, or line feeds.

This command allows you to create a string based on the ASCII collating sequence. For example, you can use this to insert a non-printing character (e.g., a tab or a carriage return) into a string.

LET <sout> = CHARACTER <val>
where <val> is a parameter or variable containing the ASCII collating sequence index values;
and <sout> is a string.

The values in <val> should be in the range 0 to 255 (real numbers will be rounded to the nearest integer). If any values outside this range are detected, an error message is printed and <sout> is not created.
