How to do basic math operations

Add background image to library
Add font file to library
Create page style
Create text style
Create Float variables VARA-C

Define a page named "pageName" with style "pageStyle"

Create minus key which decrements VarA by 1 if greater than 1 then runs mathF
Create plus key which increments VarA by 1 if less than 9 then runs mathF
Create minus key which decrements VarB by 1 if greater than 1 then runs mathF
Create plus key which increments VarB by 1 if less than 9 then runs mathF

Create text entity for VARA
Create text entity for VARB
Create Text entity for + Calc VARC
Create Text entity for - Calc VARC
Create Text entity for * Calc VARC
Create Text entity for / Calc VARC
Create Text entity for % Calc VARC

Create mathF
Displays VARA and VARB
Does Calc VARA + VARB = VARC display at text1
Does Calc VARA - VARB = VARC display at text2
Does Calc VARA * VARB = VARC display at text3
Does Calc VARA / VARB = VARC display at text4
Does Calc VARA % VARB = VARC display at text5

Run mathF func
After loading show the page named "pageName"

LIB(background,"SDHC/bground.png");
LIB(asc_16b,"SDHC/asc_16b.fnt");
STYLE(pageStyle, Page) { image = background; }
STYLE(textStyle, Text) { font=asc_16b; col=mediumblue;}
VAR(VarA,5, FLT1);VAR(VarB,8, FLT1);VAR(VarC,0, FLT1);

PAGE(pageName, pageStyle)
{

TEXT(Text4,"",textStyle, 320, 210);
TEXT(Text5,"",textStyle, 320, 250);
}

CALC(VarC,VarB,VarA,"/");TEXT(Text4,VarC);
CALC(VarC,VarB,VarA,"%");TEXT(Text5,VarC);;
}
RUN(mathF);
SHOW(pageName);
