RxUnlock

Rexx library functions: executable modules unlock, CRC32, MD5 with CD-ROM option, file compare, CPU detection, Random.

Functions

Adds function to REXX.

Removes functions from REXX (do not use).

RxBldLevel( filename )

May return

RxCpuId( Subfunction )

Subfunction '0' returns Family/Model/Stepping and a Vendor string
example results:

Intel PIII:  '681 GenuineIntel'
AMD K6:      '561 AuthenticAMD'
(first 486): '400 Unknown'
(386):       '300 Unknown'

RxCRC32( filename [, progressbar] )

Like RxMD5, 8 hexadecimal digits on success

RxExecutableType( FileName )

Returns 'NE'/'LX'/'PE'/'MZ'/etc... from executable header of FileName, else an error message starting with 'Error: '.

RxFileCompare( filename1, filename2 )

Returns 1 if files are equal and not error occurred, else 0.

This function does not compare extended attribute data.

RxMD5( filename [, progressbar] )

May return:

- 32 hexadecimal digits (success)
- 'ERROR: read error'
- 'ERROR: not CDROM'
- 'ERROR: can not open'

RxRandom ( Range )

The result is a random number within the range 0 <= X < Range.

The quality of this function is for selecting pieces of music, not for cryptographic use!

Initializes the built-in random number generator with a random value obtained from the system timer.

RxReplaceModule( SourceName, TargetName)

May not contain wild cards
In opposite to REPMOD.EXE it does NOT search .EXE files or load .DLL files to get the fully qualified name. specify the full name yourself.
Internal work is about.
- If TargetName exists, unlock it and remove any read-only attribute.
- Copy SourceName TargetName.

RxStemSearch3( searchstring, sourcestemname, targetstemname)

Use is not recommended, since it is slower than doing the query in native REXX code.

Enables display if internal function calls and results.

RxUnlockDebug( debug )

Debug is 0 or 1.

RxUnlockFiles( filespec [, filespec ..] )

Filespec may contain wild cards.
