  15. This posting and all code included in it is public domain.
  16.  
  17.    This posting presents three commands: NCAT, NCATLF, and NREV. At
  18. the end is the source code in STAR assembler in the form of a tar
  19. archive, so you can adopt the commands for use in libraries, or make
  20. other customizations. The commands included are:
  21.  
  22.  
  23.     NCAT
  24.  
  25.     Concatenate N strings
  26.  
  27.         stringN ... string2 string1 N
  28.             -->
  29.         string1+string2+...stringN
  30.  
  31.  
  32.  
  33.     NCATLF
  34.  
  35.     Concatenate N strings, but automatically add a linefeed to
  36.     each string. Useful for creating printouts and displays.
  37.  
  38.         stringN ... string2 string1 N
  39.             -->
  40.         string1+LF+string2+LF+...stringN+LF
  41.  
  42.  
  43.  
  44.     NREV
  45.  
  46.     Reverse order of N objects on the stack. Notice that N is
  47.     left in level 1.
  48.  
  49.         itemN ... item1 item2 N
  50.             -->
  51.         item2 item1 ... itemN N
  52.  
  53.  
  54.  
  55.    NCATLF is convenient for generating strings to be displayed using
  56. DISP. A linefeed will cause the remained of the string to be displayed
  57. on the next line. For instance,
  58.  
  59.     "line1" "line2" "line3" 3 NCATLF 1 DISP
  60.  
  61. will result in the equivalent of:
  62.  
  63.     "line3" 1 DISP
  64.     "line2" 2 DISP
  65.     "line1" 3 DISP
  66.  
  67.    There is no significant difference in speed (the former method is
  68. approximately 5% faster) between the two examples above. However,
  69. using NCATLF is be more convenient than using a loop to disp an
  70. arbitrary number of lines.
  71.  
  72.    Notice the reverse order of the output. This is easily corrected
  73. using NREV. Don't worry about speed; NREV will reverse 1000 objects
  74. 0.6 seconds. The following example does what one might expect:
  75.  
  76.     { "line 1" "line 2" "line 3" } OBJ-> NREV NCATLF 1 DISP
  77.
