SBM. Command
String Between delimiter Multiple
Intention
Return a delimited part of a string. You can specify multiple parts to be returned in one string. For example:
$$VAR=12*3*45*5*67
SBM.$$VAR|*|2|4|$$RES
$$RES will be 3*45*5
A example for a delimited string is a "csv" file from Excel. It could look like this:
VAR.$$TXT=Name,Last Name,Zip-Code
In this case the comma is the delimiter. Using the SBM.-command you can get any part of such delimited strings. Usage is like this:
VAR.$$TXT=Name,Last Name,Zip-Code
SBM.$$TXT|,|2|3|$$RES
DBP.$$RES
Will return "Last name,Zip-Code,", as its the second and the third part in the delimited string. Note that you will find any delimited part in the result aagain delimited with delimiters, even if there were no such delimiters in the source string. This is done to be compatible with empty delimited parts.
There is another mode of operation. Imagine the delimiter is a PIPE-Sign "|". Now the PIPE-Sign is the delimiter for the command itself, how could we do that?
We can do that with the second operation mode, we use P5. When we specify P5 then we can change the delimiter for the command itself. It's as easy as this:
' Here we have a string that is delimited with PIPE's
VAR.$$TXT=Name|Last Name|Zip-Code
' We tell SBD. that we use the comma as command-delimiter (see P5)
SBM.,$$TXT,|,2,$$RES
DBP.$$RES
' Will print: "Last Name|Zip-Code|"
As alternative, you can use the RPL.-command and replace all Pipes with something else before using SBM.
Syntax
SBM.[P6]P1|P2|P3|P4[|P5]
Parameter Explanation
P1 - STR Source string from which the part should be extracted.
P2 - Delimiter inside the source string.
P3 - Start-Index of delimited string-item to be extracted
P4 - End-Index of delimited string-item to be extracted
P5 - Variable for result. If omitted, result goes to TOS.
P6 - optional SINGLE CHAR. Delimiter for SBD itself.
Cannot be "$" or "§". If omitted its "|".

Remarks
If you have a delimited String and you want to spit all the delimited parts -each into an separate variable, best use SBD. and copy it several times for each delimited part.
