Added new _STRCMP and _STRICMP commands for quick string comparisons. Cleaned up QB64 to finish removing the QUI (quick user insert) code and folders. Altered UCASE and LCASE routines to be faster in some situations for us.

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]].

{{Cl|PRINT}} thestring

|
|
{{Cl|RSET}} anystring$ = "Hello again!"
|
|
{{Cl|PRINT}} anystring$
|
|
{{Cl|RSET}} thestring = "Over ten characters long"
|
|
{{Cl|PRINT}} thestring '' ''

{{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.
