_list Utility - Program List/Cross Reference

Location

Description

Terminal

Output will be as wide and long as the current window.

Printer

The width of the output can be either STANDARD (usually 80 columns) or COMPRESSED (usually 132 columns).

ASCII file

The output to a file will be 80 columns wide with all form feeds and carriage returns removed. The lines in the file will be separated by linefeeds only.

Listing Type

Description

Simple

A simple listing similar to the LIST verb. For example:

0010 REM "This is a remark
0020 IF A=0 THEN GOTO 0030 ELSE GOTO 0040
0030 PRINT "LINE 30"; GOTO 50
0040 FOR X=1 TO 10; PRINT X; NEXT X
0050 END

Pretty

A verb separated and indented listing. This form of listing shows a semi-block structured format. For example, THEN and ELSE will be indented from the IF verb. Lines between FOR - NEXT combinations will be indented to emphasize a block of code. For example:

0010 REM "This is a remark
0020 IF A=0
  THEN
   GOTO 0030
  ELSE
   GOTO 0040
0030 PRINT "LINE 30";
  GOTO 0050
0040 FOR X=1 TO 10;
  PRINT X;
  NEXT X
0050 END

Flow

A flow listing is similar to a pretty listing in that it also does a verb separated and indented listing. A flow listing will also draw lines indicating program flow. For example, a line with a GOTO will have a line drawn from it to the line referenced by the GOTO.

   0010 REM "This is a remark
   0020 IF A=0
     THEN
  ---    GOTO 0030
  |   ELSE
 ---+-     GOTO 0040
 | --> 0030 PRINT "LINE 30";
---+------      GOTO 0050
| |--*-> 0040 FOR X=1 TO 10;
|  |   PRINT X;
|  ---   NEXT X
-----------> 0050 END

None

No listing is output. This is used if only a cross reference is desired.

If cross referencing is selected, the following can be referenced:

• Variables

• Line numbers

• Verbs

• Functions

• I/O options

If more than one program is selected and global variable referencing is selected, all variables used will be output showing which programs they are used in.
