- ****** V X R E F **** Variables Cross Reference
-
- ..the utility to show all lines where a variable is
- used; for all BASIC programs written in GW/PC Basic
- or BASICA and saved with A-Option ( i.e. as ASCII
- File); can be run on all IBM PCs and clones of low
- compatibility with DOS 2.0 or higher.
-
- Features
-
- VXREF is was compiled by MS Quickbasic (V 4.0), thus
- it is a fast, easy to use utility. It needs a simple
- BASIC source (in ASCII) as input, the neat list is
- created directly on printer or as a print file.
-
- VXREF is migthier than other programs of that kind,
- the reason why the author made up to it. It avoids
- common errors by this way:
- - lines are n o t renumbered, whereas labels are
- discarded
- - distinction between variables and arrays of same
- name is made, e.g. A <> A(..)
- - type declarations and system variables are ignored
- as legal variables (that means DEFINT A-I,X or
- ERR, TIME$, EOF do n o t set up A,I,X or
- ERR,TIME$,EOF in the output list)
- - each occurance of a variable inside a line is men-
- tionned o n c e and does not blow up references
-
-
- How to use
-
- VXREF is evoced by typing "VX", what will start the
- compiled program VXREF . Before it make sure
-
- - that the BASIC programm to be analysed is on disk as
- ASCII file
- - there is enough work space on standard disk drive
- for the needed work file ( <= source in length)
- - the printer is ready or in case you want a print
- file theres enough space on disk
-
- After starting you are prompted for the source file's
- name; you can type drive, path etc as far as your DOS
- allows that. This name is used with extension .PRN to
- create a wanted print file. Thats all to pay atten-
- tion for...
-
- At last one warning - dont break the running VXREF
- (with CNTRL BREAK), it leaves open files on disk !
