Comment commands - start with ';'

Command lines which start with a semicolon are always considered comments and skipped when in a script or ignored typed or encountered in a series of lines sent to the device. Lines which have only spaces before the first (or "command") character are always comments. Leading spaces on any line are purged before acting on the command.

One use, for example, is to include documentation in a configuration file downloaded to the device by placing comments on each line: 

; Setup the configurations in EEPROM:
E 0x50 = "nRF PTX config:"
E 0x60 = 0x7C      ; CONFIG     (Reg. 0 = B01111100) PTX, Power Down
E 0x61 = 0x3F      ; EN_AA      (Reg. 1 = B00111111) Enable all 6
E 0x62 = 0x3F      ; EN_RXADDR  (Reg. 2 = B00111111) Enable all 6 pipes
E 0x63 = 3         ; SETUP_AW   (Reg. 3) 5-byte Rx/Tx Address width
E 0x64 = 0x34      ; SETUP_RETR (Reg. 4 = B00110010) 1 mSec, 2 retries
E 0x65 = 0x4E ;= 78  RF_CH      (Reg. 5) RF Channel = 2.478 GHz
E 0x66 = 0x06      ; RF_SETUP   (Reg. 6 = B00000110) 1 Mbps; 1.0 mW
;   ...
;
        ;  Node 1:
E 0x130 = 0x7D 0 0x3F 3 0x34 78 6 ; Alternate PRX configuration
E 0x137 = "1_SSG"       ; RX_ADDR_P0: Pipe 0 Receive address
E 0x13C = "2_SSG"       ; RX_ADDR_P1: Pipe 1 Receive address
E 0x141 = "3456"        ; Pipes 2-5 Receive addresses
E 0x145 = "1_SSG"       ; TX_ADDR = RX_ADDR_P0
E 0x14A = 0x3F 7 0x88 0xD0 7 0
E 0x150 = 0x7C          ; Alternate PTX config begins
EC 0x151 0x131 31       ; The remaining 31 bytes are the same
That use of the semicolon is demonstrated extensively throughout the MIRTOS documentation. In nearly all instances, lines which contain a semicolon are treated as comments from that point on, but not always. Here is an example where the semicolon is inside a string: 
    ; Device initialization script:
E 0xB0 = '; Bootup init: '" ; Script header (stored in EEPROM as well)
E 0xC0 = "E 1 ~= 0xC0"      ; Disable both sequencer and multitasking
E 0xCC = "N**"              ; Load the default nRF24L01 configuration
E 0xD0 = "ND+"              ; Enable the default debugging outputs
E 0xD4 = "ES 479=58"        ; DumpRegs show SP, RetAdd and SREG columns
E 0xDE = "E 0x19 = 0x25"    ; Show the heartbeat on LED #6
E 0xEC = "E 0x20 = 0x24"    ; Show the login status on LED #5
