This example creates a temporary folder name, which may already exist
and then creates a file in the folder, uses it, and then deletes the file.
EStackIndex oldTop;
FILES f1;
if (oldTop = TokenizeSymName((BYTE *) "ztemp1", 0)) {
TRY
cmd_newfold( top_estack ); /* create temporary folder */
ONERR
top_estack = oldTop;
/* Ignore error if duplicate name (folder already exists) */
if (errCode != ER_DUPLICATE_VAR_NAME)
PASS;
ENDTRY
top_estack = oldTop;
if (FS_OK == FOpen("FILE1", &f1, FM_WRITE, "DAT" )) {
/* . . . use file . . . */
FClose( &f1 );
}
FDelete( "FILE1" ); /* remove file */
