  \- symbolic constant of the population the string is in

- i

  \- allele index

## OUTPUT PARAMETERS

- none

  ## SYNOPSIS

```
#include "pgapack.h"
char  PGAGetCharacterAllele(ctx, p, pop, i)
PGAContext *ctx
int p
int pop
int i

PGAContext *ctx;
int p, q, i;
:
for (i=PGAGetStringLength(ctx, p, PGA_NEWPOP)-1; i>=0; i--)
PGASetCharacterAllele(ctx, q, PGA_NEWPOP, i,
PGAGetCharacterAllele(ctx, p, PGA_OLDPOP, i))
