LEN(string)
| LEN | Returns length of a string. |
| string | A string constant, variable, or expression. |
The LEN procedure returns the length of a string. If the string parameter is the label of a STRING variable, the procedure will return the declared length of the variable. If the string parameter is the label of a CSTRING or PSTRING variable, the procedure will return the length of the contents of the variable. Numeric variables are automatically converted to STRING intermediate values.
| Return Data Type: | UNSIGNED |
Example:
IF LEN(CLIP(Title) & ' ' & CLIP(First) & ' ' & CLIP(Last)) > 30 !If full name won't fit
Rpt:Name = CLIP(Title) & ' ' & SUB(First,1,1) & '. ' & Last !use first initial
ELSE
Rpt:Name = CLIP(Title) & ' ' & CLIP(First) & ' ' & CLIP(Last) !else use full name
END
Rpt:Title = CENTER(Cus:Name,LEN(Rpt:Title)) !Center the name in the title
