Remark: This article describes the BASIC function LEFT$ in BASIC V2 at the Commodore 64.
Typ: String Function General Programming-Syntax: LEFT$(<string>,<integer number>)
LEFT$ will be used for cutting strings into component parts beginning at the left side until to the indicated integer number. When we numerical value is 0, the outcome is a empty string (for example A$=""). When we indicated number is greater than the string, nothing will be cut.
The range of numerical values are 0 until 255. Outside the range - also negative or greater than 255 - the BASIC-error ?ILLEGAL QUANTITY ERROR IN line occurr. By using a wrong type of variable the BASIC-error ?TYPE MISMATCH ERROR in line appears. When the string or the numerical argument is missing, the BASIC-error ?SYNTAX ERROR IN line is viewed.
Examples[edit]
10 A$="SATURDAY MORNING" 20 B$=LEFT$(A$,8): PRINT B$ (SATURDAY will be cutting and print out)
10 A$="SATURDAY MORNING" 20 FOR X=0 TO LEN(A$)+1 30 PRINT LEFT$(A$,X): NEXT X
