The '''RSET''' statement right-justifies a string according to length of the string expression.

:: RSET string_variable = string_expression
|
|
|
|
|
|
|
|
* If the ''string_expression'' is longer than a fixed length string variable the value is truncated from the right side in [[LSET]] or RSET.
|
|
* If the ''string_expression'' is smaller than the fixed length, spaces will occupy the extra positions in the string.
|
|
* RSET can be used with a [[FIELD]] or [[TYPE]] string definition to set the buffer position before a [[PUT]].

''Example:''
|
|
{{CodeStart}} '' ''
|
|
{{Cl|CLS}}
|
|
{{Cl|DIM}} thestring {{Cl|AS}} {{Cl|STRING}} * 10
|
|
{{Cl|PRINT}} "12345678901234567890"
|
|
{{Cl|RSET}} thestring = "Hello!"
|
|
{{Cl|PRINT}} thestring
|
|
anystring$ = {{Cl|SPACE$}}(20)
|
|
{{Cl|RSET}} anystring$ = "Hello again!"
|
|
{{Cl|PRINT}} anystring$
|
|
{{Cl|RSET}} thestring = "Over ten characters long"
|
|
{{Cl|PRINT}} thestring '' ''
|
|
{{CodeEnd}}
|
|
{{OutputStart}}
|
|
12345678901234567890
|
|
Hello!
|
|
Hello Again!
|
|
Over ten c
|
|
{{OutputEnd}}
|
|
|
|
:''Explanation:'' Notice how "Hello!" ends at the tenth position because the length of ''thestring'' is 10. When we used SPACE$(20) the length of ''anystring$'' became 20 so "Hello Again!" ended at the 20th position. That is right-justified. The last line "Over ten c" is truncated as it didn't fit into ''thestring'''s length of only 10 characters.
