The put function can be used to convert a value of numeric data type to a character data type: the input to put can be either numeric or character, the output is always character. (Compare with input).
The format must be specified at compile time. If a dynamic format is needed at run time, putn or putc should be used.
put statement
Note: there is also a statement with the name put. This statement does not convert data types, it writes into the log.
