PB-100 Command List * Elements can be used repeatedly { } Select one of the elements [ ] Elements can be omitted Commands INPUT Function: Inputs data from the keyboard to a variable. Format: INPUT [“message statement”,] variable name * Examples: INPUT A INPUT “LOCATION”,C$,”NAME”,D$ PRINT Function: Displays an output element. Format: PRINT output element[{, or ;}] * Examples: PRINT “CASIO” PRINT A, B, C GOTO Function: Branches to a specified location. Formats: GOTO line number GOTO #program area number Examples: GOTO 210 GOTO #4 IF-THEN Function: When a branching condition is true the statements after THEN are executed. Formats: IF branching condition THEN statement IF branching condition THEN branching location Examples: IF K$=”4" THEN N=N+1 IF A>B THEN 10 IF C=4 THEN #3 FOR-TO-STEP-NEXT Function: Executes instructions between the FOR and NEXT commands a number of times specified by the control variable.
