Length
Length
Length is used to find the length of aString. Length returns the number of characters that are in aString. Note: When you want to check whether a string contains any characters, including ignorable characters, you must use the test If(Length(vtAnyText)=0) rather than If(vtAnyText=""). If the string contains for example Char(1), which is an ignorable character, Length(vtAnyText) does return 1 but vtAnyText="" returns True. This example illustrates the use of Length. The results, described in the comments, are assigned to the variable vlResult. vlResult:=Length("Topaz") ` vlResult gets 5 |
