The VBScript language is modeled on classic Visual Basic. [13] Notable features include: A "procedure" is the main construct in VBScript for separating code into smaller modules. VBScript distinguishes between a function, which can return a result in an assignment statement, and a subroutine, which cannot.
C does not provide direct support to exception handling: it is the programmer's responsibility to prevent errors in the first place and test return values from the functions.
GOTO" key on the 1982 ZX Spectrum home computer, implemented with native BASIC (one-key command entry). Goto is a statement found in many computer programming languages. It performs a one-way transfer of control to another line of code; in contrast a function call normally returns control.
As defined initially, BASIC only used line numbers for GOTO and GOSUB (go to subroutine, then return). Some Tiny BASIC implementations supported numeric expressions instead of constants, while switch statements were present in different dialects (ON GOTO; ON GOSUB; ON ERROR GOTO). Line numbers were rarely used elsewhere.
