LSET statement

Purpose | Left-align a string within the space of another string or User-Defined Type.
Syntax | LSET [ABS] result_var = string_expression [USING ustring_expression]
Remarks | LSET left-aligns a string into the space of another string or variable of a User-Defined Type.
ABS | If ABS is specified, or ustring_expression is null (empty), LSET leaves the padding positions unchanged from their original content, rather than replacing them with spaces.

USING

If string_expression is shorter then result_var, LSET left-justifies string_expression within result_var, and pads remaining character positions on the right side using the first character in ustring_expression or spaces if not specified or is null (empty).

If string_expression is longer than result_var, LSET truncates string_expression from the right until it fits in result_var.

LSET can be used to assign the content of a User-Defined Type to a User-Defined Type variable of a different class, or assign a dynamic string to a User-Defined Type. For example:

LSET MyType = STRING$(LEN(MyType), 0)

LSET MyType = a$

RSET works similarly, but performs right-justification; CSET performs center-justification.

Example | a$ = "SuperBASIC=SuperBASIC" LSET ABS a$ = "PowerBASIC" ' result: "PowerBASIC=SuperBASIC" LSET a$ = "PowerBASIC" USING "*" ' result: "PowerBASIC***********"
