Cross Ref > Commands

By Mike Prestwood

Delphi Prism versus Corel Paradox: A side by side comparison between Delphi Prism and Corel Paradox.


Common commands (procedures and functions). A function returns a value. Optionally, it may also perform an action prior to returning a value. A procedure does not return a value or it returns void or null.

Left of String

[Other Languages] 
Delphi Prism:   Substring
Syntax Example:
MessageBox.Show("Prestwood".Substring(0, 3));
Corel Paradox:   subStr

substr ( const startIndex LongInt [ , const numberOfChars LongInt ] ) String

Alternative syntax:

LeftString = subStr(NameVar, 1, 3)
Syntax Example:
�LeftString String;
  NameVar String;
NameVar = "Prestwood"
LeftString = NameVar.subStr(1, 3)
msgInfo("", LeftString)
