COMP
Compares selected items, in the same or different files, to determine the exact number and types of mismatches.
Command Class
TCL-II command.
Syntax
COMP file-specifier1 item-list1
{(options}
WITH: {(file-specifier2} {item-list2}
Syntax Elements
file-specifier1 Specifies a file containing the items to be compared.
item-list1 Specifies the items in file-specifier1 to be compared. This can be one or more item-ids separated by spaces, a list generated by a list-generating command such as SELECT, or an asterisk (*) to specify all items.
file-specifier2 Specifies a different file containing the items to be compared with the items in file-specifier1.
file-specifier2 need not be entered if the items to be compared are in file-specifier1.
item-list2 Specifies the Items in file-specifier2 to be compared with items in file-specifier1. This can be one or more item-ids separated by spaces or an asterisk (*) to specify all items.
item-list2 need not be specified if it is identical to item-list1.
Options
n Integer. Overrides the default parameter of 20 lines to search forward when trying to realign items after a misalignment has been detected. This is useful when large blocks have been inserted into or deleted from the items being compared.
A Prints all lines within the compared items. Also prints all inserted, deleted, and mismatched lines.
B Forces a page break between items.
C Suppresses comparison of DataBasic source code comment lines.
E Suppresses comparison of end of line comments in REAL assembly language source code items. (Must be used with the M option.)
I Selects item-ids for display.
M Compares items in REAL assembly language macro option format.
N Specifies the NOPAGE feature for screen listings.
P Sends all output to the printer assigned to your port.
S Suppresses the listing of item-ids of matching items.
W Formats terminal listings so that lines exceeding the specified number of display columns for a particular monitor wrap rather than truncate.
The default truncates the line at the field boundary.
Report
All lines that do not compare are displayed on the report under one of three categories, identified by a single letter:
D Deleted from the original item.
I Inserted into the second item in the comparison.
C Changed between the two items.
The COMP command automatically realigns items within the item-list.
