XSLPchgcvar

Purpose

Add or change the value of the character string corresponding to an SLP character variable

Synopsis

int XPRS_CC XSLPchgcvar(XSLPprob Prob, int nSLPCVar, char *cValue);

Arguments

Prob

The current SLP problem.

nSLPCVar

The index of the character variable being changed. An index of zero will create a new variable.

cValue

Character buffer holding the value of the character variable (not its name, which is created by XSLPaddnames if required).

Example

Assuming that character variable 7 has already been created, the following example changes its value to "new value" and creates a new character variable called BoxName with the value "Jewel box"
XSLPchgcvar(Prob,7,"new value");

XSLPchgcvar(Prob,0,"Jewel box");

XSLPgetintattrib(Prob,XSLP_CVS,&n);
XSLPaddnames(Prob,XSLP_CVNAMES,"BoxName",n,n);
Integer attribute XSLP_CVS holds the number of character variables in the problem.

Further information

Character variables can be used in formulae instead of strings, and are required in certain cases where the strings contain embedded spaces.
