variables

Define a variable with

Syntax:

var [varname]

var [varname]=[varcontent]

To call a variable, use the syntax

$[variablename]$

Example:

var myname=Andrew

echo $myname$

The above will set a variable "myname" to "Andrew" and then print:

Andrew

user input

Asks the user a question and stores the answer in a variable.

u [variablename]

u [variablename]=[question]

If a question is not specified, it will just ask the variable name as the question.

u myguess=What's your guess?

The above will ask "What's your guess?" and store the user's answer in a variable "myguess."

math

Set a variable to a mathematical output with

m

Syntax:

m [varname]=[number][operator][number]

where "operator" is +, -, *, or /

Example:

var mynumA=10

m mynumB=$mynumA$+5

echo $mynumA$ + 5 = $mynumB$

The above will set "mynumA" to 10, "mynumB" to 15, and then print:

10 + 5 = 15

round

Round a number into a variable.

Syntax:

round [varname]=[number]

Example:

var mynumA=10.5

round myroundnum=$mynumA$

round myroundnumB=15.3

The above will set "myroundnum" to 11 and "myroundnumB" to 15.

IF

Check if a condition is true.

Syntax:

if [item][compare][item]

where "compare" is =, >, <, or !
and "item" is a string, number, or variable.
Must have an

endif

to show where to skip to if condition is false.

Example:

:retry

u password=What's your password?

if $password$=andrew

    echo That's right!

    goto loggedin

endif

if $password$!andrew

    echo That's wrong.

    goto retry

endif

:loggedin

echo You're logged in!

The above will ask the user for a password and only log in when it's correct ("andrew").
