Batch Functions

Functions for Batch Files.

2009-07-19T19:43:00.001-07:00

Batch Functions is a group of programs that empower batch files with a few missing commands available in other more modern programming languages. This makes programming with batch files easier and more enjoyable.

UCase - returns an argument as uppercase.

LCase - returns an argument as lowercase.

Length - returns the length of an argument.

IsNumeric - returns true if an argument is a number and false if not.

Random - returns a random number in a given range.

SendKeys - automates the keyboard.

Random Numbers in Batch Files.

Random is a batch file function that is used to create a random whole number in a given range. Simply supply the file with two arguments, place the lesser number first, and random number will be returned to the console.

Enter the command without an argument to see usage examples.

This program is very useful for performing input validation for batch files. This command was designed to be used in conjunction with the FOR command. This will enable the command's output to be stored into a variable for later use.

For /f "tokens=*" %%a in ('Random %var1% %var2%') do (set myvar=%%a)

Batch File Command: IsNumeric

IsNumeric is a batch file function that is used to test a varible to determine if its contents are a numeric value. If the contents are numeric, the program returns a "True" to the screen and sets the error code to 0. If the contents are not numeric, the program returns a "False" and sets the error code to 1.

Enter the command without an argument to see usage examples.

This program is very useful for performing input validation. This command was designed to be used in conjunction with the FOR command. This will enable the command's output to be stored into a variable for later use.

For /f "tokens=*" %%a in ('IsNumeric %myvar%') do (set myvar=%%a)

Batch File Command: LCase

2009-07-15T09:48:00.000-07:00

LCase is a batch function that is used to lowercase all alphabetic characters in a string. For example, when using the string "Hello World!" the program would return "hello world!" to the screen. Note the batch function has no effect on numbers, spaces, or special characters.

Execute the command without an argument to see usage examples.

This program is very useful for manipulating variables in batch files. This can be accomplished by using the command in conjunction with the FOR command. This will enable the command's output to be stored into a variable for later use.

For /f "tokens=*" %%a in ('LCase %myvar%') do (set myvar=%%a)

Batch File Command: UCase

UCase is a batch function that is used to capitalize all alphabetic characters in a string. For example, when using the string "Hello World!" the program would return "HELLO WORLD!" to the screen. Note the batch function has no effect on numbers, spaces, or special characters.

Execute the command without an argument to see usage examples.

Batch File Command: Length

2009-07-15T05:19:00.000-07:00

Length is a batch function that is used to return the number of characters that make up any string that is given as an argument. For example, when using the string "Hello World!" the program would output "12" to the screen. Notice that the batch function counts both the space and the exclamation point.

Execure the command without an argument to see usage examples.
