Basic Micro Studio Syntax Manual

Modifi ers
In MBasic, all values are received and stored as binary. Modifi ers were created for formatting the
data used in commands that have input or output (SERIN / SEROUT). The modifi ers are useful for
formatting data being printed to a terminal window. All characters are represented in ASCII. Modifi ers
format the ASCII values to display properly based on the modifi er used.
An example of a command modifi er is formatting a decimal value. The decimal value 32 would output
to a terminal window as a space character. Instead, to display the actual decimal value of the variable
you would use the DEC modifi er:
Temp Var Byte
Temp = 32
serout s_out, i9600, [DEC TEMP]
The code snippet above would display the value of temp which is set to 32. If the DEC modifi er was
not used, a space character (“ “) would be displayed instead.
Several modifi ers are input only modifi ers such as WAIT which would cause an input command to
wait until the received data matches a specifi ed string.
Some modifi ers have variants. In SBIN the “S” stands for signed. Where in IBIN the “I” represents
the indicator. The indicator is the symbol used to indicate the numeric type such as binary (%) or
hexadecimal ($).
Modifi ers can be used with the following commands:
Output Modifi ers Input Modifi ers
DEBUG DEBUGIN
I2COUT I2CIN
OWOUT OWIN
SEROUT SERIN
HSEROUT HSERIN
LCDWRITE LCDREAD
WRITEDM
DTMFOUT
DTMFOUT2
READDM
Output modifi ers can also be used to modify array variables:
string var byte(100)
string = “Hello World” ;string(0-10)=”Hello World”
string = dec 1234567 ;string(0-6)=”1234567”
string = ihex 0x3456 ;string(0-4)=”$3456”
