LSet
Left-justifies a string
Declare Sub LSet ( ByRef dst As String, ByRef src As Const String )
Declare Sub LSet ( ByVal dst As WString Ptr, ByVal src As Const WString Ptr )
LSet dst, src
LSet dst_udt, src_udt
dst
LSet left justifies text into the string buffer dst, filling the left part of the string with src and the right part with spaces. The string buffer size is not modified.
If text is too long for the string buffer size, LSet truncates characters from the right.
For compatibility with QBasic, LSet can also copy a user defined type variable into another one. The copy is made byte for byte, without any care for fields or alignment. It's up to the programmer to take care for the validity of the result.
Syntax
Declare Sub LSet ( ByRef dst As String, ByRef src As Const String )
Declare Sub LSet ( ByVal dst As WString Ptr, ByVal src As Const WString Ptr )
Usage
LSet dst, src
LSet dst_udt, src_udt
Parameters
dst
String String to receive the data.
srcSource String to get the data.
dst_udtUser defined Type to receive the data.

Example
Dim buffer As String
buffer = Space(10)
LSet buffer, "91.5"
Print "-[" & buffer & "]-"
buffer = Space(10)
LSet buffer, "91.5"
Print "-[" & buffer & "]-"
Type mytype1

Dim a As mytype1 , b As mytype2
b.z = 1234
LSet a, b
Print a.x

LSet a, b
Print a.x
Differences from QB
- In QB, the syntax was LSet dst = src. That syntax is also supported by FB.
