/* Implementation notes:
|
|
|
43 |
*
|
|
|
44 |
* For cannot be nested (no "FOR ... do FOR ..." allowed)
|
|
|
45 |
*
|
|
|
46 |
* When executed, FOR allocates a "FOR context" to RMOD's memory, this context
|
|
|
47 |
* holds the memory state of a FindNext iteration, as well as the command
|
|
|
48 |
* to run on each matched file.
|
|
|
49 |
*
|
|
|
50 |
* This FOR context is looked at by command.c and used to provide a command
|
|
|
51 |
* instead of getting the command from interactive cli or BAT file. Repeats
|
|
|
52 |
* until the FindNext buffer stops matching files.
|
|
|
53 |
*
|
|
|
54 |
* This file only provides the help screen of FOR, as well as the FOR-context
|
|
|
55 |
* initialization. Actual execution happens within command.c.
