Constant

  • PI (3.14159)

Variables

  • Variable names have to start with A-Z and range between 1E-39 and 1E38.
  • String variable names end with a $ e.g. TEXT$. The user has to supply the starting address of the string in the coresponding variable TEXT.
  • Only one dimensional arrays are possible. The number of elements in the array must be specified in a DIM statement. The user has to supply the starting address of the array in the memory in the coresponding variable.
    e.g.: meas=#4100: DIM MEAS(20): MEAS(9)=542: PRINT MEAS(9)

Expressions

  • FREE returns the number of bytes left in the page
  • PAGE returns the current page number
  • RND returns a random number between 0 and 1
  • STAT returns the value of the INS8060 Status Register
  • TOP returns the highest address of the NIBL program in the current page

Program entry

  • AUTO n generates line numbers starting at number n (ctrl c to quit)
  • AUTO n,m generates line numbers starting at n with increment m (ctrl c to quit)
  • BYE quit floating point basic
  • EDIT n allows for editing of line n. Characters may be inserted with cntrl Q and deleted with cntrl X, cntrl C will exit EDIT
  • LINK x link with user routine
  • LIST
  • LIST n
  • LIST n-m
  • NEW
  • NEW x

Decleration Statements

  • CLEAR clears all variables and stacks
  • DATA
  • DEF FN
  • DIM
  • LET

DEF FN must be followed by a character A-Z, so 26 user defined functions are possible. An expression between brackets can be added to transfer a parameter e.g.: DEF FNA (SQROOT) = SQR(SQROOT) INPUT A PRINT FNA(A): REM prints square root of A
DEF FNB = SIN(X)+1 INPUT X PRINT FNB

Program Flow Control

  • DO / UNTIL
  • END
  • FOR / NEXT / STEP
  • GOTO
  • GOSUB / RETURN
  • ON ... GOSUB / GOTO
  • IF ... THEN ...: ELSE
  • IF ... THEN n: ELSE
  • IF ...: ELSE
  • READ
  • RESTORE
  • RESTORE n
