echo $1 >> $2
else

Hello,
I'm trying to write a while loop for a decimal value in tcsh which I know can't be done. Instead I want my increments to be one order of magnitude too large and then divide it by 10 when I use the variable. However, I don't know how to divide my variable and set it as another.

Hiii
I actually intent to check the integer or floating point number input by user i.e. 23, 100, 55.25, 12.50 ..etc. However, when someone input strings or alpha character, my program has to show invalid input.!! Is there any Unix shell script syntax can help me to check ?

Hi,
Need help on this. I need to increment a variable by 1 but retain as 2 characters.
I am using expr to do additions:
NEWSERIAL=`expr $SERIAL + 1`
$SERIAL can range from 01-99. After adding "1", I need the result to be 2 characters, eg: 02+1 = 03. By default expr will truncate the... (4 Replies)
Hi guys...

glpixelzoom
GLPIXELZOOM(3G)GLPIXELZOOM(3G)NAME
glPixelZoom - specify the pixel zoom factors
C SPECIFICATION
void glPixelZoom( GLfloat xfactor,
GLfloat yfactor )
PARAMETERS
xfactor, yfactor Specify the x and y zoom factors for pixel write operations.
DESCRIPTION
glPixelZoom specifies values for the x and y zoom factors. During the execution of glDrawPixels or glCopyPixels, if (xr, yr) is the cur-
rent raster position, and a given element is in the mth row and nth column of the pixel rectangle, then pixels whose centers are in the
rectangle with corners at
(xr+n.xfactor, yr+m.yfactor)
(xr+(n+1).xfactor, yr+(m+1).yfactor)
are candidates for replacement. Any pixel whose center lies on the bottom or left edge of this rectangular region is also modified.
Pixel zoom factors are not limited to positive values. Negative zoom factors reflect the resulting image about the current raster posi-
tion.
ERRORS
GL_INVALID_OPERATION is generated if glPixelZoom is executed between the execution of glBegin and the corresponding execution of glEnd.
ASSOCIATED GETS
glGet with argument GL_ZOOM_X
glGet with argument GL_ZOOM_Y
