EVAL is my tool for execute script or solve expression using variables. Variables only accept string or numbers. For string variables use the $ identifier, for numeric variables use the # identifier.
This tool have the next mainly functions for execute script:
ExeBasic()
SetValue()
SetTextValue()
GetValue()
GetTextValue()
SetMaxVariables()
SetMaxLines()
ExeBasic()
Execute script in Basic (only function and sentences documented in last page of this help).
Syntax: ExeBasic StringCode, Handle, Mode
Where StringCode is a variable with the code to execute, Handle may be set to 0 and is for future use. Mode may be set to 0 or 1 (0=initialize 1=preserve variables). If Mode is set to 0 then clear or initialize all in memory. If is set to 1 then preserve variables but initialize number of lines and buffers internally.
SetValue()
Set a value in a numeric variable.
Syntax: SetValue VarName, Value, Mode
VarName must be a variable name of numeric type. For example a name of numeric variable may be VARNUM#. Value must have the numeric value to set variable. Mode is for clear or preserve previous values of other variables.
SetTextValue()
Set a value in a string variable.
Syntax: SetTextValue VarName, stringValue, Mode
VarName must be a variable name of string type. For example a name of string variable may be VARNUM$. stringValue must have the value for set text variable. Mode is for clear or preserve previous variables.
GetValue()
Get value from a numeric variable.
Syntax: GetValue(VarName)
Return the value of a numeric variable. By example: RESULT=GetValue(“VARNUM#”)
GetTextValue()
Get value from a string variable.
Syntax: GetTextValue(VarName)
Return the value of a string variable. By example: RESULT$=GetTextValue(“VARNUM$”)
SetMaxVariables()
Syntax: SetMaxVariables maxvar
Allow set the max number of variables availables example: SetMaxVariables 1000
SetMaxLines()
Syntax: SetMaxLines maxlines
Allow set the max number of lines availables example: SetMaxLines 1000
