LEFT(string [,length])
| LEFT | Left justifies a string. |
| string | A string constant, variable, or expression. |
| length | A numeric constant, variable, or expression for the length of the return string. If omitted, length defaults to the length of the string. |
The LEFT procedure returns a left justified string. Leading spaces are removed from the string. Spaces are padded on the right to return a string of the “length” specied. To remove trailing spaces use CLIP(LEFT())
Return Data Type: STRING
Examples:
| LEFT(' ABC') returns 'ABC ' |
| ! | | CompanyName = LEFT(CompanyName) !Left justify the company name | | ! |
| IF FILEDIALOG('Pick file',FileName) THEN |
| IF LEFT(FileName,2)='\\' THEN |
| STOP('\\UNC paths are not supported!') |
| ELSIF UPPER(LEFT(FileName,11))='C:\WINDOWS\' THEN |
| STOP('Do not select Windows folder!') |
| END |
| END |
| ! | | MESSAGE('Sub Total $' & CLIP(LEFT(FORMAT(Inv:PmtTotal,@n-15.2))) & ' plus…') | | ! |
| IF LEFT(CardNo,1) = '4' THEN |
| CardType = 'VISA' |
| ELSIF LEFT(CardNo,2) >= '50' AND LEFT(CardNo,2) <;= '55' |
| CardType = 'MC' |
| ELSIF LEFT(CardNo,4) = '6011' |
| CardType = 'DISC' |
