type=char, int, long, double

Prompt - prompt string

Exp - some arithmetic expression

From-exp - starting value

To-exp - ending value

Step-exp - increment

Cond - conditional =,<,<=,>,>=, and, or

 but you cannot compare strings

Cond - conditional =, <, <=, >, >=, and, or

But you cannot compare strings

Parameter={BYREF|BYVAL} var {AS type}

Parameter is a dim-like statement

No arrays are allowed.  BYREF indicates passing by reference BYVAL indicates pasing by value.  Type is char, int,long, double

Parameter={BYREF|BYVAL} var {AS type}

Parameter is a dim-like statement

No arrays are allowed.  BYREF indicates passing by reference BYVAL indicates pasing by value.  Type is char, int,long, double

Declare the value of the returned function by setting the name of the function to a value

Routine-name = exp

OPEN pathname {FOR mode} AS filnumber

Mode = {READ|WRITE|APPEND}

Pathname=string of a file name

Filenumber= value from 0 to 65535

Mode=access mode

Opens a file for access.  Note that opening for read destroys old content.  File writing is constrained to 23KB

CLOSE {filenumber}

Filenunber = value from 0 to 65535

Closes a file.  Specifying no filennumber closes all files currently open

PUT filenumber, {bytepos},{var}

Bytepos - position in the file to write to

Var - variable to write

Writes a var to a file at bytepos.  If bytepos is omitted the var is written to the current pos. if the var is ommitted the file is positioned at the pos and no var is written

GET filenumber, {bytepos},{var}

Bytepos - position in the file to read from

Var - variale to read into

Reads a var from a file at bytepos. If bytepos is omitted the vari is read from the current pos.  if the var is omitted the file is positioned at the pos and no var is read.

PRINT #filemumber, (obj…)

Obj - a variable or expression or quoted string

Puts text output to the file specified by filenumber

CLS

Clear the screen

Paper n

Paint the screen the color 'n'

Ink n

Set the color of text, lines, and points

Point x,y

Y - the y coordinate (-80 to +80)

Set a single pixe on the display

In the current ink color

Line x0,y0,x1,y1

X1 - the right-most point

Y0 - the left most point

Y1 -the right most point

Draw a line on the display in he current ink color

Geometric mathemetaticl fucntion

Beep n

0-silence     1-bleep

2-oh no       3-laser

4-too bad     5-computing

6-carnival     7-completed task

Makes noises on the cybiko

WAIT n

N - number of 10ths of seconds to wait

Waits 10ths of seconds

KEY

Acts as a variable holding the most recently type keyboard variable.  See the documenation for more info

WHILE exp1 cond exp2

See IF command, above

Initiates a while loop that exectes allcommands up to the WEND command.  IF the conditional is still true, processing continues at the WHILE command

WEND

Terminates the while command

TYPE {decl, …}

Decl is as in DIM

Creates a structured datatype

END TYPE

Ends a type definition

PRINTXY x, y {,vals}

X,Y=the coordinate where the text will display

Vals are values as in print to be displayed

Positions the cursor on the screen and prints the values

RIGHT dest, src, len

Src = source string

Dest = destination string

Len = the number of bytes from the end of the src string to copy to the dest string

Copies bytes from the right-hand side of the src string to the left hand side of the dest string

MID dest, src, start{, len}

Src = source string

Dest= destination String

Start = where in the src string to start copying

Len = number of bytes to copy

Copies from the middle of the soruce string to the destination string. If the length is left out it copied all bytes from the source string start point to the end
