What Are The Built-in Functions In Pl/1?

Answer»

Built-in functions: PL/I provides almost 200 built-in functions, pseudovariables, and subroutines that manipulate scalar and aggregate data. These functions cover:

  • Character, Bit, and Graphic string manipulation (e.g. INDEX, CENTER)
  • ARITHMETIC computation (e.g. MAX, RANDOM)
  • MATHEMATICAL computation (e.g. ATANH, GAMMA)
  • Floating point inquiries (e.g. HUGE, TINY)
  • Floating point manipulation (e.g. SUCC, SCALE)
  • Integer manipulation (e.g. IAND, RAISE2)
  • Precision handling (e.g. BINARY, UNSIGNED)
  • Array manipulation (e.g. HBOUND, SUM)
  • Storage control (e.g. EMPTY, ADDR)
  • Condition handling (e.g. ONCHAR, ONLOC)
  • Input/Output (e.g. COUNT, FILEOPEN)
  • Date/Time manipulation (e.g. DATETIME, DATE)
