XSLPchgcvar
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.
