Option (1) -- This option determines whether CONCAT will be in verbose or quiet mode by default. The default may be toggled by using the command line "Q" option. Option (2) -- The two operating modes are concatenation of the source files into a new destination file, as the name of the program implies, and appending the source files to an already existing destination file. As released the default is CONCAT. You can make APPEND the default, if you do more appending than concatenating. The mode selected can be changed by the command line options "C" and "A". Option (3) -- This file format option determines how CONCAT joins the files. In TEXT mode the files are joined wherever the CP/M end-of-file character is found, even in the middle of a sector. In BINARY (object) mode the files are joined only on record boundaries and the end-of-file character is ignored. TEXT is the correct setting for most uses, but if you use CONCAT mostly for binary files (for some strange reason!), you can make that the default here. The format selected can be changed by the command line options "T" and "O". Option (4) -- As distributed CONCAT checks for adequate space before doing any writing to disk. If you're courageous, you can turn off this feature by toggling it to NO. Space checking can then be turned back on by using the command line "S" option. Option (5) -- In concatenation mode CONCAT transfers the create date stamp of the first source file to the new file. (If any source file has the same name as the destination file, its file stamp will be used instead.) If you prefer, change this option to NO to turn this function off by default. It can then be turned back on with the command line "F" option. Option (6) -- If the "D" option is used to insert the current date and time into the destination file, the date will ordinarily be in AMERICAN format (December 13, 1990). If you wish, you can select EUROPEAN format here (13 Dec 90). Option (7) -- If the "D" option is used to insert the current date and time into the destination file, the time will ordinarily be in CIVILIAN format (3:21 pm). If you wish, you can select MILITARY format here (15:21). Option (8) -- This option selects the default case of the divider string if it is entered from the command line. It does not affect the operation of the "%<" and "%>" escape sequences, nor does it affect the internally configured divider string.
