[[LSET]] left-justifies a fixed length string expression based on the size of the [[STRING]] variable and string expression.


{{PageSyntax}}
: [[LSET]] {stringVariable = stringExpression | stringExpression1 = stringExpression2}


{{PageDescription}}
* 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 LSET string expression is smaller, spaces will occupy the extra positions to the right in the string. 
* LSET can be used with a [[FIELD]] or [[TYPE]] definition to set the buffer position before a [[PUT]].

''Example 2:'' How LSET can define two different string length values in one statement.
{{CodeStart}}

{{Cl|TYPE}} ninestring
head {{Cl|AS}} {{Cl|STRING}} * 9
{{Cl|END TYPE}}

{{Cl|TYPE}} fivestring
head AS {{Cl|STRING}} * 5
{{Cl|END TYPE}}

{{Cl|DIM}} me {{Cl|AS}} ninestring, you {{Cl|AS}} fivestring
me.head = "ACHES NOT"
{{Cl|CLS}}

{{Cl|LSET}} you.head = me.head
{{Cl|PRINT}} "me.head: "; me.head
{{Cl|PRINT}} "you.head: "; you.head
{{CodeEnd}}
{{OutputStart}}
