What It Does

SFormat is passed a host-string and 1 to 9 replacement sub-strings. The host string contains replacement markers for each sub-string. The function returns a formatted string where all markers are replaced with the passed sub-strings. A replacement marker is defined as the % symbol followed by the replacement number. The first replacement marker is %1, the second is %2 and so on.

Examples

The following example will return "Hello, John how are you today".

Move (SFormat("Hello, %1 how are you today", "John")) to sReply

Replacement markers may be placed in any order and used more than once. The following example will return the string "I want to say Hello, Goodbye, Hello".

Move (SFormat("I want to say %2, %1, %2","Goodbye", "Hello")) to sReply

This function is used extensively by the packages to support multi language text. For example:

Send Log_Status (SFormat(C_$EndProcessNumberOfErrors, Process_Title(self), ErrCount))

where the constant C_$EndProcessNumberOfErrors is defined in a separate language package. The English version of this constant is "End Process: %1 (number of errors=%2)"

Notes

Note that the above sample passes the replacement parameter ErrCount as an integer. The integer will be converted to a string before being inserted into the host string. This can be a useful automatic conversion technique.

If your host string needs to display % symbol followed by a number, you should use %% instead of % to represent the text. The following example will return "This first parameter %1, will get replaced with coffee".

Move "coffee" to sSomeSymbol

Move (SFormat("This first parameter %%1, will get replaced with %1, sSomeSymbol)) to sReply
