String Expressions

String expressions result in the creation of a character string. String expressions include:

  • String constants. If a string constant contains any spaces or symbols, it must be delimited by single or double quotes. String constants can also be ASCII, EBCDIC, or hexadecimal.
  • Two or more expressions combined with the concatenation operator "|". For example:

    %%x = %%y | %%z | string

  • A string function. For example:

    %%x = SUBSTR(%%y, 2, 10)
