Introduction/Summary
DOSPLUS 3.5 HELP/CMD Disassembly - The Syntax Help of the Commands (Model I)
HELP/CMD shows the syntax and the parameters of a DOSPLUS 3.5 library command or utility, run from the DOS command level as HELP [FROM] command [TO] fs/@ds. It is a load module of 9 blocks, 1809 bytes, at 5200H-5906H and 5A2AH-5A33H with the transfer address 5200H, after the two comment records (the name HELP and the copyright notice). The code (5200H-534FH) and the dictionary (5350H-5505H) are the same in both models apart from addresses; the Model III texts show the optional parts in [ ] where the Model I has < >, and are 8 bytes longer, so every address after them is 8 higher on the Model III, as is LOCDCB% (4488H on the Model I, 44A0H on the Model III). This page is the Model I one.
The Parts of HELP/CMD
| Address | Contents |
|---|---|
| 5200H-5231H | EVAL@ and the output: @DO, a device, or a file opened by INIT@ (5200H). |
| 5232H-525CH | The name compared with the words of the dictionary (5232H). |
| 525DH-5288H | The text of a command (525DH). |
| 5289H-530EH | Routines: a byte of a text, a character and a tab, the column count, the output, the close of a file, a line (5289H, 52B5H, 52D1H, 52E8H, 52F2H, 5301H). |
| 530FH-534FH | The list of the commands, and an error (530FH, 534BH). |
| 5350H-5505H | The dictionary of 89 words (5350H). |
| 5506H-58BDH | The 49 texts (5506H). |
| 58BEH-5A33H | The heading of the list, the variables and the evaluation block ([58BEHH], [5A2AHH]). |
How HELP Works
EVAL@ puts the first field of the command line into the source block (58E6H) and a second field, or the field after TO, into the destination block (5909H); the evaluation block names the same block for the wildmask, so a field with a wildcard is taken as the output too, and its parameter block is empty. With no destination the output is device 1, @DO (520FH). A destination with a name is opened as a file by INIT@, with the text of the field as its file control block and a buffer of 256 bytes (5221H); any other destination is taken by the number in bits 0-2 of its flag byte and LOCDCB%% (522BH), so that a drive :d as the destination sends the output to the device numbered d (:2 is @PR). Every character goes out through the ROM's 001BH (52E8H), and a file is closed when HELP ends (52F2H).
The name is compared with the first 49 words of the dictionary (5232H). A word matches only when the name ends, with its 03H, where the word ends: HELP takes no abbreviations, and a name with an extension or a drive matches nothing. A match shows the text of the same number (525DH); no match, or no name, shows the heading HELP is available for the following: and the 49 words, five to a row in columns of 12 (530FH). Word 39 is a carriage return: it ends the row of SCREEN, SYSTEM, TIME and VERIFY, and the tab and the end of the row after it make a line of 12 spaces before the nine utilities.
The texts are tokenized: a byte of 80H and up is a word of the dictionary, numbered by its bits 0-6 (5289H), so that the names of the commands, the keywords FROM, TO and USING, the kinds of field (fs, @ds, :dr, wildmask) and value (=switch, ='string', =value) and the names of the common parameters are each stored once. A tab moves to the next multiple of 15 columns in a text and of 12 in the list; the width is stored into the SUB at 52C0H (525EH, 5310H), and the column is counted by 52D1H.
Differences from the Manual
The manual (Utilities, HELP) gives the syntax and the list of the commands and utilities, the example HELP COPY and the output to a device (HELP ATTRIB TO @PR), and HELP agrees with it. The manual does not say that the name must be given in full, that the output may also be a file, or that a drive given as the output is taken as a device number. The texts themselves differ from the commands in one place: the text of FORMAT gives SIZE=value, a parameter FORMAT/CMD does not have; its count of sides is SIDES (5B61H), and EVAL@ does not take SIZE as an abbreviation of it.
The Model I list and texts name seven utilities that are not on the Model I master: CONVERT, DIRCHECK, DISKDUMP, MAP, PATCH, RESTORE and SYSGEN; only BACKUP and FORMAT of the nine are there. The Model I texts also differ from the Model III ones in three places: CONFIG lists HC=value for a rigid drive, CREATE gives DATA=switch, and SYSTEM has no MODE and PORT.

Disassembly
5200H - HELP
HELP/CMD's transfer address, entered from the DOS command level with Register Pair HL at the command line after the word HELP: HELP [FROM] command [TO] fs/@ds. EVAL@ takes the name asked about into the source block at 58E6H and an output file or device into the block at 5909H. HELP compares the name with the first 49 words of its dictionary (5350H): a match shows the text of that command, any other name, or none, shows the list of the 48 commands and utilities HELP knows. The output goes to @DO, or to the device or the file given, and a file is closed at the end. HELP returns to the DOS by RET, or leaves through ERROR@.

Point Index Register IX to 5A2AH, HELP's evaluation block for EVAL@: the source and destination blocks and an empty parameter block.
5204
GOSUB to 4479H, EVAL@, to take the fields of the command line at Register Pair HL into the blocks of Index Register IX.
5207
If the NZ FLAG is set (EVAL@ returned an error code in Register A), JUMP to 534BH to post it through ERROR@.
520A

AND Register A with the flag byte at Index Register IX+00H: the Z FLAG when neither a destination nor a wildmask field was given.
520F
LD A,01H 3E 01
Load Register A with 01H, the number of the device @DO, the display; the load leaves the Z FLAG of the AND as it was.
5211
If the Z FLAG is set (no destination field), JUMP to 5229H to find the DCB of device 01H, @DO, from Register A.
5213

LD A,(DE) 1A
Load Register A with the flag byte of the destination block at Register Pair DE: bit 6 a name, bits 0-2 a device number.
5217
INC DE 13
INCrement Register Pair DE by 1, to 590AH, the text of the field, which becomes the file control block of an output file.
5218

5229
AND 07H E6 07

5232H - Look Up the Name
The name in the source block is compared with the words of the dictionary, the first character of each without its bit 7; a word matches when the name ends (03H) where the word does. Register B counts the words from 1; at 32H (50) the 49 words with a text have all failed.

Test bit 7 of the byte at Register Pair HL: set at the first character of the next word, so at the end of this one.
524C
If the Z FLAG is set (the word goes on), LOOP BACK to 5241H to compare the next two characters.
524E
LD A,(DE) 1A
Load Register A with the character of the name at Register Pair DE that follows the length of the word.
524F
CP 03H FE 03
Compare Register A against 03H: the Z FLAG when the name ends there too, so that the whole name matches the word.
5251
If the Z FLAG is set (a match), JUMP to 525DH to show the text numbered by Register B.
5253
DEC HL 2B
DECrement Register Pair HL by 1, back to the last character of the word, for the pass to the next word below.
5254

INCrement Register B by 1, the number of the next word and of its text.
525DH - Show the Text of a Command
Reached with Register B = the number of the word that matched, 1 (APPEND) to 49 (SYSGEN). The text of that number, counted from 5506H, is shown after a carriage return, with its tabs at every 15 columns; a carriage return ends the last line when it is not empty, and an output file is closed.

LD A,0DH 3E 0D
Load Register A with 0DH, a carriage return; the load leaves the flags of the OR as they were.

5288
RET C9
RETurn to the DOS, which called HELP from the command level: the end of HELP after a text.
5289H - Show a Byte of a Text
Register Pair HL points to a byte of a text: below 80H a character (09H a tab, 0DH a carriage return), 80H and above the word of the dictionary numbered by its bits 0-6. Entered at 528AH with the byte in Register A by the list (530FH). Register Pair HL returns at the next byte, and the Z FLAG when that byte is 03H, the end of the text.

49 texts, one for each of words 0-48, each ended by 03H; text n is found by passing n - 1 bytes 03H from 5506H (526BH). A byte below 80H is a character (09H a tab to the next column of 15, 0DH a carriage return), a byte of 80H and up a word of the dictionary. Each row below is one line of the screen; its comment gives the line as HELP shows it, (tab) for a tab. Text 40, that of the carriage return of word 39, is empty, and no name can reach it.
