21 interpreted as a string compares less than 3, while as an integer, it compares greater. This is valid for bash; maybe someone can comment on other shells.
That's good one.. it clears useless use of < and > while numeric comparison.. removed from numeric comparison...Smilie

As explained in my previous post < and > signs treats as string so they compare each digit by digit. such as..

Code:
$ [[ 211 > 12 ]] && echo gt || echo lt        # Here it compares 2 with 1 so 2 is greater than 1 as per sort pattern so gt.
gt

$ [[ 211 > 32 ]] && echo gt || echo lt         #Here it compares 2 with 3 so 3 is greater than 2 as per sort pattern so lt.
lt

Thanks Rudic...

voice_set_playmode(3alleg4)					  Allegro manual				       voice_set_playmode(3alleg4)

NAME
voice_set_playmode - Adjusts the loop status of the specified voice. Allegro game programming library. SYNOPSIS
#include <allegro.h> void voice_set_playmode(int voice, int playmode); DESCRIPTION
Adjusts the loop status of the specified voice. This can be done while the voice is playing, so you can start a sample in looped mode (hav- ing set the loop start and end positions to the appropriate values), and then clear the loop flag when you want to end the sound, which will cause it to continue past the loop end, play the subsequent part of the sample, and finish in the normal way. The mode parameter is a bitfield containing the following values: PLAYMODE_PLAY Plays the sample a single time. This is the default if you don't set the loop flag. PLAYMODE_LOOP Loops repeatedly through the sample, jumping back to the loop start position upon reaching the loop end. PLAYMODE_FORWARD Plays the sample from beginning to end. This is the default if you don't set the backward flag. PLAYMODE_BACKWARD Reverses the direction of the sample. If you combine this with the loop flag, the sample jumps to the loop end position upon reaching the loop start (ie. you do not need to reverse the loop start and end values when you play the sample in reverse). PLAYMODE_BIDIR When used in combination with the loop flag, causes the sample to change direction each time it reaches one of the loop points, so it alternates between playing forwards and in reverse.
