8BIT OPERATING SYSTEM FOR ZX-SPECTRUM
 \history \doors2000
DOORS 2000 (a part 6)
(Year 2000, the wind of the changes which have broken a roof, at all..)
mzINITFunction mzINIT - initialization kernalja disk operations Doors. It is caused once before start of system (OS) or own program. Has no parameters and does not demand entering data. On an output as does not give out any variables.
mzADDDRFunction mzADDDR - ADD DRIVER. Adds in system the concrete driver. In register pair BC the address of the driver in memory is set. In reg. D - the bank of memory is set. In reg. E - a logic name of the device from 0 ? (A - Z) and all!!!
IN: In BC - the address of the driver, D - bank, E - eia.ono?-in
OUT: by default there are no target data
mzADDDRFFunction mzADDDRF - ADD DRIVER. Adds in system the concrete driver. It is reserved for further use here again it will not be described.
ATTENTION! It is recommended to use only mzADDDR.
mzDELDRFunction mzDELDR - DELETE DRIVER. Disconnects particularly set driver from system. In accumulator A - the logic name of the device is set.
IN: In A - a logic name of the device
OUT: by default there are no target data
mzCURDRFunction mzCURDR - establishes the current device by default. In accumulator A - the logic name of the device is set.
IN: In A - a logic name of the device
OUT: by default there are no target data
Variables
(Variables D2k)
Variables in Doors 2000 happen two types: cleanly information and then from them it is possible to read out only a condition (R/O - read only) and significant, i.e. having changed in them value is possible change of adjustments and the further work kernalja (R/W - read / write).
| Name | Type | Byte | Comments | | pFLAG | R/O | 1 | > If value not 0 then there is a reprint of a window | | gSTREL | R/O | 1 | Whether> the arrow Is included? Not 0 - it is included | | pTEKID | R/W | 1 | > Indetefikator appendices | | pTEKSD | R/W | 2 | > the Index of a current window | | gKLFL | R/W | 1 | > the Index of an operating mode of the standard driver of the keyboard: bit0 = LAT (0)/RUS (1), bit1 = None (0)/Caps (1), bit2 = On (0)/Off (1) | | gDOBCLK | R/O | 1 | > If not 0 then has occured DoubleClick | | gCO_NEW | R/W | 2 | > Coordinates of an arrow | | pMEMDRV | R/O | 2 | > the Address of the driver of memory | | rPAG | R/O | 1 | > Current page of memory | | rPAGES | R/O | 1 | > Eie-in pages of memory of all | | pLASTC | R/O | 2 | > Last pressed key |
