During the execution of an object program referring to the PROGRAM Library rou-
tines, the following error codes may be printed on the Teleprinter Output unit when
error conditions are encountered by the specified subroutine:

Error Code      Subroutine      Condition

  02 UN         ALOG            x <= 0

  03 UN         SQRT            x < 0

  04 UN         .RTOR           x = 0, y <= 0
                                x < 0, y != 0

  05 OR         SIN, COS        |x| > 2**14

  06 UN         .RTOI           x = 0, i <= 0

  07 OF         EXP             |x| * log2(e) > 124

  08 OF         .ITOI           i**j out of range

  08 UN         .ITOI           i = 0, j <= 0

  09 OR         TAN             |x| > 2**14
