STRING ENDS WITH

STRING ENDS WITH

Let Subcommand

Return a 1 if a string ends with a specified substring and a 0 if it does not.

LET <iflag> = STRING ENDS WITH <s1> <s2>
where <iflag> is a parameter containing a 1 if <s1> ends with <s2> and 0 otherwise;
            <s1> is the name of a pre-existing string;
and     <s2> is the name of a pre-existing string.

LET IFLAG = STRING ENDS WITH S1 S2

The strings on the right hand side of the equal sign must be previously existing strings. That is, expressions are not allowed. For example, the following will result in an error message
LET IFLAG = STRING ENDS WITH "alan.heckert@nist.gov" "nist.gov"

you need to do

LET STRING SORG = alan.heckert@nist.gov
LET STRING SMATCH = nist.gov
LET SOUT = STRING ENDS WITH SORG SMATCH


The name on the left hand side of the equal sign should either be a previously existing parameter or not previously defined. If it is a previously existing string, variable, or matrix name, an error will be reported and the requested parameter will not be created.

The total number of characters that DATAPLOT can use for storing functions and strings is set when DATAPLOT is built. The current default (11/2008) is 50,000 characters. Previous versions may set this limit at 1,000 or 10,000 characters. This limit applies to the combined number of characters for all functions and strings.
