Description
• The STRING$ function returns the specified character for the specified number of times.
• Specify the number of characters in the string obtained in <numeric expression 1>.
• If <character string expression> is used to specify the character, only the first character in
the string is valid. If <numeric expression 2> is used to specify the character, it indicates
that the character code is to be repeated. The allowable specification range of the value is
from 0 to 255. If a value greater than 255 is specified, an "Illegal function call" error occurs.
• It is not allowed to specify a full-byte character in <character string expression> or
<numeric expression 2>. If it is specified, the operation cannot be performed normally.
