Use BLIST to produce a formatted listing of a mvBASIC program. Output is sent to the printer unless the T (terminal) option is specified.
Format
BLIST filename progname-list [(options)] |
Parameter(s)
filename |
Name of a file that contains mvBASIC programs. |
|
progname-list |
Item-IDs of the programs you want to list. An asterisk (*) specifies all programs in the file. |
|
options |
The following options are supported: |
|
n |
Number of a line. |
|
n-m |
Specifies a range of lines. |
|
D |
Double-spaces lines. |
|
T |
Displays output on the screen. |
|
Description
BLIST indents five spaces to make room for statement labels. All other indents are three spaces. You can use the Editor to modify these default values by changing line 4 of the Command Definition item in the Master Dictionary. Line 4 contains:
004 0503 |
05 specifies the first indent, 03 specifies subsequent indents.
NOTE |
BLIST does not follow the standard TCL convention of sending output to the screen. You must explicitly specify the T option from BLIST to send output to the screen. |
Listing an mvBASIC Program
The following example lists a portion of the program FX. Since the T option was not specified, output is sent to the printer:
>BLIST BASICLIB FX
